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