virtual

(PHP 3, PHP 4, PHP 5)

virtual -- Perform an Apache sub-request

Description

bool virtual ( string filename )

virtual() is an Apache-specific function which is equivalent 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 only supported when PHP is installed as an Apache module.

Parameters

filename

The file that the virtual command will be performed on.

Return Values

Performs the virtual command on success, or returns FALSE on failure.

ChangeLog

VersionDescription
4.0.6 This function may be used on PHP files. However, it is typically better to use include() or require() for PHP files.

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: As of PHP 4.3.3 you can use this function with the NSAPI server module in Netscape/iPlanet/SunONE webservers, too.
