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. For PHP files, you need to
use include() or require();
virtual() cannot be used to include a document
which is itself a PHP file.
