virtual
(PHP 4, PHP 5)
virtual — Perform an Apache sub-request
说明
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.

| 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
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: 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。
