$_GET - HTTP GET variables
An associative array of variables passed to the current script via the URL parameters.
$HTTP_GET_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_GET_VARS and $_GET are different variables
and that PHP handles them as such)

Example #1
$_GET example
<?php
echo 'Hello ' . htmlspecialchars($_GET["name"]) . '!';
?>
Assuming the user entered http://example.com/?name=Hannes
The above example will output something similar to:
Hello Hannes!
Note
This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script.
There is no need to do global $variable; to access it within functions or methods.
Note
The GET variables are passed through urldecode(3).
Handling external variables, The filter extension.

VIRTUAL(3) 1 VIRTUAL(3)virtual - Perform an Apache sub-requestSYNOPSIS
bool virtual (string $filename)
DESCRIPTION virtual(3) is an Apache-specific function which is similar to <!--#include virtual...--> in mod_include. It performs an Apache sub-request.
It is useful for including CGI scripts or .shtml files, or anything else that you would parse through Apache. Note that for a CGI script,
the script must generate valid CGI headers. At the minimum that means it must generate a Content-Type header.
To run the sub-request, all buffers are terminated and flushed to the browser, pending headers are sent too.
This function is supported when PHP is installed as an Apache module or by the NSAPI server module in Netscape/iPlanet/SunONE webservers.
PARAMETERS
o $filename
- The file that the virtual command will be performed on.
RETURN VALUES
Performs the virtual command on success, or returns FALSE on failure.
EXAMPLES
See apache_note(3) for an example.
NOTES
Warning
The query string can be passed to the included file but $_GET is copied from the parent script and only $_SERVER['QUERY_STRING'] is
filled with the passed query string. The query string may only be passed when using Apache 2. The requested file will not be listed
in the Apache access log.
Note
Environment variables set in the requested file are not visible to the calling script.
Note
This function may be used on PHP files. However, it is typically better to use include(3) or require(3) for PHP files.
SEE ALSO apache_note(3).
