virtual
virtual is an Apache-specific function which is similar 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 supported when PHP is installed as an Apache module webserver.
Parameters
- uri
-
The file that the virtual command will be performed on.
Return Values
Performs the virtual command on success, or returns false on failure.
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:
Environment variables set in the requested file are not visible to the calling script.
Note:
This function may be used on PHP files. However, it is typically better to use include or require for PHP files.
