virtual

Perform an Apache sub-request (PHP 3, PHP 4, PHP 5)
bool virtual ( string filename )

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.

此函数仅在 PHP 作为 Apache 模块安装时才可使用。

参数

filename

The file that the virtual command will be performed on.

返回值

Performs the virtual command on success, or returns FALSE on failure.

更新日志

版本说明
4.0.6 This function may be used on PHP files. However, it is typically better to use include() or require() for PHP files.

注释

警告:

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.

注意:

Environment variables set in the requested file are not visible to the calling script.

注意:

自 PHP 4.3.3 起也可以在 Netscape/iPlanet/SunONE 服务器的 NSAPI server module 中使用本函数。
