Description
int
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.
| Warning |
This function works only when PHP is compiled as an Apache module,
since it uses the Apache API for doing sub requests. 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.

As of PHP 4.0.6, you can use virtual() on PHP files.
However, it is typically better to use include() or
require() if you need to include another PHP file.
Note: As of PHP 4.3.3 you can use this function with the
NSAPI server module in Netscape/iPlanet/SunONE
webservers, too.
