在文档root之外执行PHP脚本？

Question

我有以下目录结构：

/htdocs
     ├──test
     │     └──.htaccess
     └──myphp.php

/htdocs是https://example.com和/htdocs/test 的根是http://test.example.com 我的目标是执行myphp.php脚本并将fileName作为参数传递，当client requests ./ images/* ie https://example.com/test/ images/blah.png或http://test.example.com/images/blah.png

为此，我正在使用mod-rewrite apache2 。

RewriteEngine On 
RewriteRule ^(images/.*)$ ../myphp.php?$1 [L]

​错误400（不良请求），带有http://test.example.com/images/blah.png

如果我尝试.htaccess中的绝对路径，

RewriteRule ^(images/.*)$ /htdocs/myphp.php?$1 [L]

我会得到错误403（禁止）：

如果没有硬编码域名的情况，如何在可能的情况下进行此工作？
