virtual

(PHP 3, PHP 4, PHP 5)

virtual -- Perform an Apache sub-request

說明

bool virtual ( string filename )

virtual() is an Apache-specific function which is similar to  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.

此函數僅在 PHP 作為 Apache 模組安裝時才可使用。

參數

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.

更新日誌

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

注解

警示

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

注: 自 PHP 4.3.3 起也可以在 Netscape/iPlanet/SunONE 伺服器的 NSAPI server module 中使用本函數。
