virtual
(PHP 3, PHP 4 )
virtual -- Perform an Apache sub-request
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.
