Php Files Warning: Mkdir() [function.mkdir]: Permission Denied
mkdir permission denied 777
I had difficulty using mkdir() function until I set the above folder permission to 777. So anytime you write files or create directories using php, check your folder permissions using your cpanel's file manager. 755 did not help only 777 would work for me.

$topDir=dirname(__FILE__);
$folder0="/".$PHPfolder;
$source_dir = $topDir."/"; //.$folder0."/";
if(is_dir($topDir."/BACKED")==false){ mkdir($topDir."/BACKED", 0777,true); }

Php Files Making An Image Viewer
files images viewer
Sometimes i have pictures that people want to view but are too numerous or inconvenient to email.
I just do a batch conversion on the images (I use Irfan view a free app) and upload them to a new folder I called "stylists". Using this script in an index.php, I dump it with the pictures. It will show them in your browser.

[Create image viewer]
$imagedirectory="../stylists/";
$dir = opendir($imagedirectory);

while ($file = readdir($dir)){
//for ($i=1; $i<=500; $i++){
// $file = readdir($dir);
$fullpath=$current_dir.$file;

echo "

$file
";
}
closedir($dir);
?>

You can tweak it to your folder requirements

Php Files Reading TXT Files
fclose fgets fopen fread filesize feof read file whole line character
[Reading the Whole File]
The fread function reads a number of bytes from a file, up to the end of the file (whichever comes first). The filesize function returns the size of the file in bytes, and can be used with the fread function, as in the following example.

$listFile = "junk.txt";
if (!($fp = fopen($listFile, "r")))
exit("Unable to open the input file, $listFile.");
$buffer = fread($fp, filesize($listFile));
print "$buffer
\n";
fclose($fp);
?>

[Reading Line by Line]
The fgets function is used to read a line at a time. The function takes two parameters, the file handle, and the number of bytes to read. The function reads data up to a new line, or the number of bytes specified (whichever comes first), and returns the line read. The following is an example of using the fgets function.

if (!($fp = fopen("junk.txt", "r")))
exit("Unable to open the input file.");
while (!feof($fp))
{
$buffer = fgets($fp, 1024);
print "$buffer
\n";
}
fclose($fp);
?>

[Reading a Character at a time]
The fgetc() function is used to read a single character from a file.

Note: After a call to this function the file pointer has moved to the next character.

Example
The example below reads a file character by character, until the end of file is true:

if (!($f=fopen("welcome.txt","r")))
exit("Unable to open file.");
while (!feof($f))
{
$x=fgetc($f);
echo $x;
}
fclose($f);
?>

Php Files Write To Txt File
fopen fwrite rewind fopen write file
Write Text to File
The easiest way to write text to a file in PHP is by using the file_put_contents() function, which handles opening, writing, and closing the file automatically. If you need more control, you can use the traditional fopen() and fwrite() method.

Method 1: The Quickest Way (file_put_contents)

This method overwrites the file by default or creates it if it doesn't exist.
?php
$file = 'log.txt';
$text = "Hello, World!n";

// Overwrite file content (or create file if it doesn't exist)
file_put_contents($file, $text);

Use code with caution.

To Append Text (Don't Overwrite)


Pass the FILE_APPEND flag as the third parameter to add text to the end of the file.
php

?php
$file = 'log.txt';
$text = "This line is appended.n";

// Append text to the file
file_put_contents($file, $text, FILE_APPEND);

Use code with caution.
Method 2: The Traditional Way (fopen + fwrite)
Use this if you are performing multiple write operations on an open file stream.

$file = 'log.txt';
$text = "Writing with fwrite.n";

// Open file for writing ('w' overwrites, 'a' appends)
$handle = fopen($file, 'w') or die('Cannot open file');

// Write data
fwrite($handle, $text);

// Always close the handle
fclose($handle);

Use code with caution.
Quick Reference: File Modes for fopen

'w' (Write-only): Erases the file content or creates a new file if it doesn't exist.

'a' (Append): Preserves existing data and moves the pointer to the end of the file.


Writing to Files
The fwrite function is used to write a string, or part of a string to a file. The function takes three parameters, the file handle, the string to write, and the number of bytes to write. If the number of bytes is omitted, the whole string is written to the file. If you want the lines to appear on separate lines in the file, use the \n character. Note: Windows requires a carriage return character as well as a new line character, so if you're using Windows, terminate the string with \r\n.

The following example logs the visitor to a file, then displays all the entries in the file.

$logFile = "stats.txt";
// Open the file in append/read mode
$fp = fopen($logFile, "a+");
// Create a string containing the user details
$userDetails = $HTTP_USER_AGENT;
if (isset($HTTP_REFERER))
$userDetails = $userDetails . " $HTTP_REFERER
\r\n";
else
$userDetails = $userDetails . "
\r\n";
// Write the user details to the file
fwrite($fp, "$userDetails");
// Move to the start of the file
rewind($fp);
$entries = 0;
// Display each line in the file
while(!feof($fp))
{
$buffer = fgets($fp, 1024);
if ($buffer != "")
{
print $buffer;
$entries++;
}
}
// Show a summary
print "There are $entries entries in the log file
";
fclose ($fp);
?>
Insert Character by Position
these are results for php read text line by line and insert character in position 9 of each line
Search instead for php read text line by line and insert character in poition 9 of each line
AI Overview
You can read a text file line by line in PHP using fgets() or file() and insert a character at position 9 using substr_replace()
[?php
function insert_character($value){
$inputFile = 'input.txt';
file_put_contents($inputfile, $value);
$outputFile = 'output.txt';
$charToInsert[0] = $_POST["char1"];$charToInsert[1] = $_POST["char2"]; // Change to your desired character
$position[0] = $_POST["pos1"]; $position[1] = $_POST["pos2"]; // 0-indexed position 9 (10th character)
$handle = fopen($inputFile, 'r');
$output = fopen($outputFile, 'w');

if ($handle && $output) {
while (($line = fgets($handle)) !== false) {
// Remove trailing newline for accurate length/position handling
$eol = '';
if (substr($line, -1) === "n" || substr($line, -1) === "r") {
$eol = PHP_EOL;
$line = rtrim($line, "rn");
}

// Insert character if line is long enough, otherwise pad or append
if (strlen($line) >= $position) {
$newLine = substr_replace($line, $charToInsert, $position[0], 0);
} else {
// Optional: pad with spaces if line is shorter than 9 chars
$newLine = str_pad($line, $position[0], ' ') . $charToInsert[0];
}

fwrite($output, $newLine . $eol);
}

fclose($handle);
fclose($output);
if (file_exists($outputfile)) {
return file_get_contents($outputfile);
//echo $text;
} else { echo "File not found.";}

echo "Processing complete!";
} else {
echo "Error opening files.";
}
}
?]
Key Functions Usedfopen(): Opens the source file for reading and a destination file for writing.
fgets(): Reads the file line by line safely to conserve memory.
substr_replace(): Inserts the character at the specified index without removing existing text (using a length of 0).

if (copy($source, $destination)) {
echo "File copied successfully!";
} else { echo "Failed to copy file."; }

Keeping the Same Filename Dynamically


If you have a path to a folder and want to keep the original file's name, combine copy() with basename() to extract the filename

$sourceFile = 'uploads/images/photo.jpg';
$targetDir = 'archive/';

// Safely joins the directory and the original file name
$destinationFile = $targetDir . basename($sourceFile);

if (copy($sourceFile, $destinationFile)) { echo "File copied to: " . $destinationFile; }

} else { echo "copy problem ".$source; exit; }
} else { echo "file $source does not exist."; }
// look for htacess
$source = __DIR__ ."/".$value. '/.htaccessBKUP';
$destination = __DIR__ ."/".$value. '/.htaccess.php';
if (file_exists($source)) {
if (copy($source, $destination)) {
touch($destination); //echo "Config file restored successfully.";
} else { echo "copy problem ".$source; exit; }
} else { echo "file $source does not exist."; }

}
echo "It has run";
?]

Merge Many Files Into One [?php
$file1 = 'destination.txt';
$file2 = 'source_to_merge.txt';

// Read the contents of the second file
$contents2 = file_get_contents($file2);

// Append it to the destination file
// FILE_APPEND prevents overwriting the existing data in destination.txt
file_put_contents($file1, $contents2, FILE_APPEND); ?]

Move Files$old_path = 'images/photo.jpg';
$new_path = 'archive/photo.jpg';

// Ensure the target directory exists before moving
if (!is_dir('archive')) { mkdir('archive', 0755, true); }

// Move the file
if (rename($old_path, $new_path)) {
echo "File moved successfully.";
} else { echo "Failed to move the file."; }



To copy a file in PHP, you use the built-in
copy() function. This function takes the source file path and the destination path as arguments and returns true on success or false on failure.
Syntax
php

bool copy(string $source, string $destination, resource $context = null): bool

$source (Required): The path to the original file you want to copy.
$destination (Required): The path, including the new filename, where the file will be copied. If the destination file already exists, it will be overwritten.
$context (Optional): A context resource created with stream_context_create().

Example
Here is a basic example of how to copy a file and check the result:

=?php

// Specify the source file path
$source_file = 'path/to/original_file.txt';

// Specify the destination path, including the new filename
$destination_file = 'path/to/new_directory/copied_file.txt';

// Use the copy() function
if (copy($source_file, $destination_file)) {
echo "File copied successfully!";
} else {
echo "Something went wrong while copying the file. Check permissions.";
}

?=

Important Considerations

File Permissions: The PHP script must have permission to read the source file and write to the destination directory. Permission errors are a common reason for failure.
Destination Path: The destination must include the new filename, not just the directory name. For example, you need .../new_dir/copied.txt, not just .../new_dir/.
Error Handling: The copy() function returns a boolean, so it is important to use an if statement to handle potential errors gracefully.
Moving vs. Copying: If you want to move a file (delete the original after copying), use the rename() function instead.
Uploaded Files: For handling files uploaded via an HTML form (HTTP POST method), you must use the specialized move_uploaded_file() function, not copy().

============
Save the above file as SimpleImage.php and take a look at the following examples of how to use the script.

The first example below will load a file named picture.jpg resize it to 250 pixels wide and 400 pixels high and resave it as picture2.jpg

include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resize(250,400);
$image->save('picture2.jpg');
?>
If you want to resize to a specifed width but keep the dimensions ratio the same then the script can work out the required height for you, just use the resizeToWidth function.

include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToWidth(250);
$image->save('picture2.jpg');
?>
You may wish to scale an image to a specified percentage like the following which will resize the image to 50% of its original width and height

include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->scale(50);
$image->save('picture2.jpg');
?>
You can of course do more than one thing at once. The following example will create two new images with heights of 200 pixels and 500 pixels

include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToHeight(500);
$image->save('picture2.jpg');
$image->resizeToHeight(200);
$image->save('picture3.jpg');
?>
The output function lets you output the image straight to the browser without having to save the file. Its useful for on the fly thumbnail generation

header('Content-Type: image/jpeg');
include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToWidth(150);
$image->output();
?>
The following example will resize and save an image which has been uploaded via a form

if( isset($_POST['submit']) ) {
include('SimpleImage.php');
$image = new SimpleImage();
$image->load($_FILES['uploaded_image']['tmp_name']);
$image->resizeToWidth(150);
$image->output();
} else {
?>



}

Syntax:

preg_replace( $pattern, $replacement, $subject, $limit, $count )

Return Value: This function returns an array if the subject parameter is an array, or a string otherwise.

Example: In this example we use preg_replace to remove non-numeric characters from a string, leaving only the numbers. It then prints the extracted numbers from the string.


// PHP program to illustrate
// preg_replace function

// Declare a variable and initialize it
$geeks = 'Welcome 2 Geeks 4 Geeks.';

// Filter the Numbers from String
$int_var = preg_replace('/[^0-9]/', '', $geeks);

// print output of function
echo("The numbers are: $int_var n");
?>
Output
The numbers are: 24
===========================================
filter_var
You can use filter_var and sanitize the string to only include integers.
$s = "Lesson 001: Complete";
echo filter_var($s, FILTER_SANITIZE_NUMBER_INT);
==========================================

$s = "Lesson 001: Complete";
preg_match("/([0-9]+)/", $s, $matches);
echo $matches[1];
==========================================
number_format (1234.567);
//Returns the number 1,235
number_format (1234.567, 2);
//Returns the number 1,234.57

number_format (1234.567, 2, ',', ' ');
//Returns the number 1 234,57

number_format (1234.567, 1, 'a', 'b');

Php Function Ziping And Unziping Server Folders Using Php
zip unzip directory folder backup mysql backup directory
// I use a browser script that send the proper data to back up since if have multiple accounts. I separate the small files in one zip and large files in another. Under case 1. you will notice mp3 and zip this prevents bloated zips which may fail. Video and music should be done seperately from the rest of the files. I included a mysql backup that gets the data and makes a .sql file if you give it database information.

Php Function Preg_match Is The Ereg Replacement
ereg eregi preg_match preg match clean
$text = "Start    middle    end";

// Inserts
strictly before any group of non-breaking spaces
$newText = preg_replace('/(&$nbsp;)+/', '
$0', $text);
echo $newText;


To remove "weird" characters (like malformed UTF-8, symbols, emojis, or control characters) from a string while keeping standard alphanumeric text, spaces, and punctuation, you should use the PHP function preg_replace() with a Unicode regular expression
$string = "Hello, World! “This� is crazy... ???? Keep this? No #weird stuff. 123.";

// Keeps letters, numbers, spaces, punctuation (p{P}), and currency/math symbols (p{S})
$clean = preg_replace('/[^p{L}p{N}sp{P}p{S}]+/u', '', $string);

echo $clean;
// Output: Hello, World! This is crazy... Keep this? No #weird stuff. 123.


If you define "punctuation" strictly as standard keyboard characters (.,;:!?@#-$%^&*()_+=[]{}|/<>~'"), it is often safer to explicitly whitelist exactly what you want to keep.

$string = "Hello, World! “This� is crazy... ???? Keep this? No #weird stuff. 123.";

// Whitelist: letters, numbers, spaces, and standard keyboard punctuation marks
// Note: The hyphen (-) is placed at the very end so it isn't treated as a range
$clean = preg_replace('/[^A-Za-z0-9 .,;:!?()[]{}'"@#$%^&*_+=/\|<>`~-]/', '', $string);

echo $clean;
// Output: Hello, World! This is crazy... Keep this? No #weird stuff. 123.


preg_match() Would be the pcre equivalent. The patterns will pretty much be the same, only real difference is that the preg_xxx functions require an opening/closing delimiter in the pattern and modifiers (if needed) are specified after the closing delimiter.

So for instance:
ereg(".",$var1)
would be
preg_match("~.~",$var1) // ~ is used as the pattern delimiter.
or for instance,


eregi(".",$var1) // case in-sensitive
would be
preg_match("~.~i",$var1) // i modifier added to make it case in-sensitive

if(eregi("color",$fieldName))

preg_match("~color~i",$fieldName))

Php Function Get Current Directory Name And Path In PHP
working directory list path file
Directory
Use the getcwd() Function to Get the Current Directory Name in PHP
Use the dirname() Function to Get the Current Directory Name in PHP
Use the basename() Function to Get the Current Directory Name in PHP

Use the getcwd() Function to Get the Current Directory Name in PHP
The getcwd() function gives the current working directory. The returned value is a string on success.

The function does not take any parameters. The function returns false in case of failure.

Let�s consider the following directory structure.

??? var
? ??? www
? ??? html
| ???project
| ???index.php
The PHP file lies inside the project directory. The getcwd() function will return the name of the current working directory, which is project.

We can use the echo function to display the content of the function. We can see in the output section that the getcwd() function returns the current working directory with its path.

echo getcwd();
Output:

/var/www/html/project
Use the dirname() Function to Get the Current Directory Name in PHP
We can also use the dirname() function to get the current directory name in PHP. The function returns the path of the parent directory.

It accepts two parameters where the first one is the path and the second one is levels. Levels indicate the number of directories to move up.

Finally, we can use the __FILE__ magic constants in the dirname() function to get the name of the current directory. The __FILE__ constant returns the full path of the current file along with the file name.

We can demonstrate these constants and the function in the above directory structure. For example, we get the following result when we echo the __FILE__ constant from the index.php file.

echo __FILE__;
Output:

/var/www/html/project/index.php
For example, write the dirname() function in the index.php file with the __FILE__ constant as the parameter.

echo dirname(__FILE__);
$topDir=dirname(__FILE__);
Output:

/var/www/html/project
In this way, we can get the current working directory name in PHP.

Use the basename() Function to Get the Current Directory Name in PHP
We can use the basename() function to get the current working directory name without the path in PHP. We can apply this function with the result of the above two functions.

The basename() function returns the name of the base file or folder from the given path. For example, if the path provided is /var/www/html/project, the output will be project.

For example, use the functions dirname(__FILE__) and getcwd() as the parameters for the basename() function. In this way, we can get the current working directory name in PHP.

echo basename(dirname(__FILE__))."
";
echo basename(getcwd())."n";
Output:

Directory List
$current_dir="./uploads/";
$dir = opendir($current_dir);
echo "directory=".$current_dir;
while ($file = readdir($dir)){
$fullpath=$current_dir.$file;
$filedate=date('Y-m-j', filemtime($fullpath));
$fsize=filesize($fullpath)/1000;
$fsize=(int)$fsize;$fsize=$fsize/1000;
$bulletin[]=$file."@".$fsize."@".$filedate;
}
closedir($dir);
$count1=count($bulletin);
sort($bulletin);
reset($bulletin);

19 IMAGETYPE_AVIF
Note:

exif_imagetype() will emit an E_NOTICE and return false if it is unable to read enough bytes from the file to determine the image type.

Example 2



In PHP, you can determine the file type of a movie, PDF, or image using several functions. mime_content_type() returns the MIME type, finfo provides more detailed information, and exif_imagetype() is specifically for images.
Detailed Explanation:

1. mime_content_type():
This function uses the magic.mime file to return the MIME type of a file. For example:

mime_content_type('movie.mp4') might return video/mp4.

mime_content_type('document.pdf') might return application/pdf.
mime_content_type('image.jpg') might return image/jpeg.

2. finfo:
This function provides more detailed information about a file, including its type. It can be used to check for specific file types or extensions.
3. exif_imagetype():
This function is specifically designed for images. It reads the first few bytes of an image file to determine its type. It can be used to verify that a file is actually an image before processing it further.

Example:
Code

// Check file type using mime_content_type()
$file = 'movie.mp4';
$mime_type = mime_content_type($file);

if ($mime_type == 'video/mp4') {
echo "The file is a video.";
} elseif ($mime_type == 'application/pdf') {
echo "The file is a PDF.";
} elseif (strpos($mime_type, 'image/') !== false) { // Check if MIME type starts with 'image/'
echo "The file is an image.";
} else {
echo "The file type is unknown.";
}

// Check file type using finfo (more robust)
$finfo = finfo_open(FILEINFO_MIME_TYPE); // Open a fileinfo handle
$mime_type = finfo_file($finfo, $file, FILEINFO_MIME_TYPE);
finfo_close($finfo);

if ($mime_type == 'video/mp4') {
echo "The file is a video (finfo).";
} elseif ($mime_type == 'application/pdf') {
echo "The file is a PDF (finfo).";
} elseif (strpos($mime_type, 'image/') !== false) {
echo "The file is an image (finfo).";
} else {
echo "The file type is unknown (finfo).";
}

// Check image type using exif_imagetype()
$file = 'image.jpg';
$image_type = exif_imagetype($file);

if ($image_type == IMAGETYPE_JPEG) {
echo "The file is a JPEG image.";
} elseif ($image_type == IMAGETYPE_PNG) {
echo "The file is a PNG image.";
} elseif ($image_type == IMAGETYPE_GIF) {
echo "The file is a GIF image.";
} else {
echo "The file is not a supported image type.";
}

?>

Key Considerations:

Security:
.

Always validate file types on the server-side to prevent malicious files from being uploaded.
MIME Type vs. File Extension:
.
File extensions can be easily spoofed, so relying solely on them is not secure. MIME types provide a more reliable indication of file content.
finfo for Detailed Information:
.
finfo can be used to check for specific file types or extensions, providing more flexibility than mime_content_type().
exif_imagetype() for Image Validation:
.
This function is specifically designed for images and can be used to verify that a file is actually an image before processing it.

is_dir($path): Returns true if it’s a directory.
is_link($path): Returns true if it’s a symbolic link.

Php Server Get Ipaddress
ipaddress
Reading Serve Ip
To read your
server's internal IP address in PHP, you should use the $_SERVER['SERVER_ADDR'] superglobal. For the server's external (public) IP address, the most reliable way is to query an external service.
Internal Server IP Address
The $_SERVER superglobal array contains various server and request-related information. The SERVER_ADDR key typically holds the IP address of the host server running the script.
php

$server_ip = $_SERVER['SERVER_ADDR'];
echo "Server Internal IP Address: " . $server_ip;
?>

Note: This may return 127.0.0.1 (localhost) in some configurations or if running from a command line interface (CLI).
External Server IP Address
To get the IP address that your server uses to communicate with the internet (its public IP), you generally need to make a request to an external service that simply echoes back the IP address it sees.
A common and reliable method is to use Amazon's check IP service via file_get_contents() or curl.
php

// Use file_get_contents to fetch the IP from a reliable external service
$external_ip = file_get_contents('https://checkip.amazonaws.com');

// Filter and validate the IP address before use
if (filter_var($external_ip, FILTER_VALIDATE_IP) !== false) {
echo "Server External IP Address: " . trim($external_ip);
} else {
echo "Could not retrieve external IP address.";
}
?>

Alternative Methods

Using DNS: If your server has a domain name, you can use PHP's gethostbyname() function to find the IP associated with that hostname.
php

$domain_name = 'yourdomain.com';
$ip_from_dns = gethostbyname($domain_name);
echo "IP from DNS lookup: " . $ip_from_dns;
?>

Using Sockets (Linux/Unix): A more robust dynamic method, especially useful in CLI environments, involves connecting to a public DNS server (like Google's 8.8.8.8) to determine the outgoing interface IP address.
php

$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_connect($sock, '8.8.8.8', 53);
socket_getsockname($sock, $addr);
socket_close($sock);
echo "Server Outgoing IP: " . $addr;
?>



$ip=$_SERVER['REMOTE_ADDR'];

if($_SERVER['REMOTE_ADDR']=="208.73.252.147"){

function get_ip() {
if ( ! empty( $_SERVER['HTTP_CLIENT_IP'] ) ) {
//check ip from share internet
$ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif ( ! empty( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
//to check ip is pass from proxy
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}
return $ip;
}

Php Server Server Information - Using The $_SERVER
server information function
URL INFO [USE parse_url under langueage

'PHP_SELF'
The filename of the currently executing script, relative to the document root. For instance, $_SERVER['PHP_SELF'] in a script at the address http://example.com/test.php/foo.bar would be /test.php/foo.bar. The __FILE__ constant contains the full path and filename of the current (i.e. included) file. If PHP is running as a command-line processor this variable contains the script name since PHP 4.3.0. Previously it was not available.
'argv'
Array of arguments passed to the script. When the script is run on the command line, this gives C-style access to the command line parameters. When called via the GET method, this will contain the query string.
'argc'
Contains the number of command line parameters passed to the script (if run on the command line).
'GATEWAY_INTERFACE'
What revision of the CGI specification the server is using; i.e. 'CGI/1.1'.
'SERVER_ADDR'
The IP address of the server under which the current script is executing.
'SERVER_NAME'
The name of the server host under which the current script is executing. If the script is running on a virtual host, this will be the value defined for that virtual host.
'SERVER_SOFTWARE'
Server identification string, given in the headers when responding to requests.
'SERVER_PROTOCOL'
Name and revision of the information protocol via which the page was requested; i.e. 'HTTP/1.0';
'REQUEST_METHOD'
Which request method was used to access the page; i.e. 'GET', 'HEAD', 'POST', 'PUT'.

Note:

PHP script is terminated after sending headers (it means after producing any output without output buffering) if the request method was HEAD.

'REQUEST_TIME'
The timestamp of the start of the request. Available since PHP 5.1.0.
'REQUEST_TIME_FLOAT'
The timestamp of the start of the request, with microsecond precision. Available since PHP 5.4.0.
'QUERY_STRING'
The query string, if any, via which the page was accessed.
'DOCUMENT_ROOT'
The document root directory under which the current script is executing, as defined in the server's configuration file.
'HTTP_ACCEPT'
Contents of the Accept: header from the current request, if there is one.
'HTTP_ACCEPT_CHARSET'
Contents of the Accept-Charset: header from the current request, if there is one. Example: 'iso-8859-1,*,utf-8'.
'HTTP_ACCEPT_ENCODING'
Contents of the Accept-Encoding: header from the current request, if there is one. Example: 'gzip'.
'HTTP_ACCEPT_LANGUAGE'
Contents of the Accept-Language: header from the current request, if there is one. Example: 'en'.
'HTTP_CONNECTION'
Contents of the Connection: header from the current request, if there is one. Example: 'Keep-Alive'.
'HTTP_HOST'
Contents of the Host: header from the current request, if there is one.
'HTTP_REFERER'
The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.
'HTTP_USER_AGENT'
Contents of the User-Agent: header from the current request, if there is one. This is a string denoting the user agent being which is accessing the page. A typical example is: Mozilla/4.5 [en] (X11; U; Linux 2.2.9 i586). Among other things, you can use this value with get_browser() to tailor your page's output to the capabilities of the user agent.

'HTTPS'
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
Set to a non-empty value if the script was queried through the HTTPS protocol.

Note: Note that when using ISAPI with IIS, the value will be off if the request was not made through the HTTPS protocol.

'REMOTE_ADDR'
The IP address from which the user is viewing the current page.
if($_SERVER['REMOTE_ADDR']=="127.0.0.1"){ $server='localhost';$user='greatone';$password='gr38t0n3';$database='angel'; $_SESSION['LEVEL']=10;}
else{ $server="localhost";$user="angelde_flunky1";$password="wied55";$database="angelde_a1"; }

'REMOTE_HOST'
The Host name from which the user is viewing the current page. The reverse dns lookup is based off the REMOTE_ADDR of the user.

Note: Your web server must be configured to create this variable. For example in Apache you'll need HostnameLookups On inside httpd.conf for it to exist. See also gethostbyaddr().

'REMOTE_PORT'
The port being used on the user's machine to communicate with the web server.
'REMOTE_USER'
The authenticated user.
'REDIRECT_REMOTE_USER'
The authenticated user if the request is internally redirected.
'SCRIPT_FILENAME'

The absolute pathname of the currently executing script.

Note:

If a script is executed with the CLI, as a relative path, such as file.php or ../file.php, $_SERVER['SCRIPT_FILENAME'] will contain the relative path specified by the user.

'SERVER_ADMIN'
The value given to the SERVER_ADMIN (for Apache) directive in the web server configuration file. If the script is running on a virtual host, this will be the value defined for that virtual host.
'SERVER_PORT'
The port on the server machine being used by the web server for communication. For default setups, this will be '80'; using SSL, for instance, will change this to whatever your defined secure HTTP port is.
'SERVER_SIGNATURE'
String containing the server version and virtual host name which are added to server-generated pages, if enabled.
'PATH_TRANSLATED'
Filesystem- (not document root-) based path to the current script, after the server has done any virtual-to-real mapping.

Note: As of PHP 4.3.2, PATH_TRANSLATED is no longer set implicitly under the Apache 2 SAPI in contrast to the situation in Apache 1, where it's set to the same value as the SCRIPT_FILENAME server variable when it's not populated by Apache. This change was made to comply with the CGI specification that PATH_TRANSLATED should only exist if PATH_INFO is defined. Apache 2 users may use AcceptPathInfo = On inside httpd.conf to define PATH_INFO.

'SCRIPT_NAME'
Contains the current script's path. This is useful for pages which need to point to themselves. The __FILE__ constant contains the full path and filename of the current (i.e. included) file.
'REQUEST_URI'
The URI which was given in order to access this page; for instance, '/index.html'.
'PHP_AUTH_DIGEST'
When doing Digest HTTP authentication this variable is set to the 'Authorization' header sent by the client (which you should then use to make the appropriate validation).
'PHP_AUTH_USER'
When doing HTTP authentication this variable is set to the username provided by the user.
'PHP_AUTH_PW'
When doing HTTP authentication this variable is set to the password provided by the user.
'AUTH_TYPE'
When doing HTTP authenticated this variable is set to the authentication type.
'PATH_INFO'
Contains any client-provided pathname information trailing the actual script filename but preceding the query string, if available. For instance, if the current script was accessed via the URL http://www.example.com/php/path_info.php/some/stuff?foo=bar, then $_SERVER['PATH_INFO'] would contain /some/stuff.
'ORIG_PATH_INFO'
Original version of 'PATH_INFO' before processed by PHP.
