使用根目录之外的 php 文件的 HTML 表单操作?

I am wondering, there are a few files I have kept outside of the root directory in a different directory and I am trying to use a HTML form to post info to a php file that sits OUTSIDE the root directory

Is that possible? If so, how?

Make a proxy script... something which is inside the web directory, but all it does is include the appropriate "protected" file:

DOCROOT/form_handler.php

<?php
include "../secret/form_handler.php";

DOCROOT/form.html

...
<form action="form_handler.php">
...

This is, in fact, how many sites are setup (in essence at least). It is typical to place most of your scripts outside the DOCROOT like this for in the rare case where Apache or similar does not parse your PHP (i.e. if it is misconfigured), it doesn't inadvertently send your source code.
