(PHP 4, PHP 5)
virtual — Perform an Apache sub-request
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.
Тази функция се поддържа само, ако PHP е инсталирано като модул на Apache.
The file that the virtual command will be performed on.
Performs the virtual command on success, or returns FALSE on failure.
|4.0.6||This function may be used on PHP files. However, it is typically better to use include() or require() for PHP files.|
See apache_note() for an example.
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.
Забележка: Environment variables set in the requested file are not visible to the calling script.
Забележка: От PHP 4.3.3 може да използвате тази функция с NSAPI сървърен модул в Netscape/iPlanet/SunONE уеб сървъри също.
