PHP Include Path Problems

Setting the include path is really confusing me. I must be missing something important.

So I have the following scripts in the public_html folder of my server.

    photoGallery.php
    header.php

I have my htaccess file set to redirect a url with the following structure to photoGallery.php

RewriteRule ^gallery/([^/]+)/([0-9]+)-([^/]+)$ photoGallery.php?imageName=$2 [L]

So something like this...

http://localhost/gallery/roofing/1-picture-of-roofing

Would resolve to...

http://localhost/photoGallery.php?imageName=1

The problem is there is a PHP include inside of photoGallery.php that will not resolve if the URL has been rewritten.

    include 'header.php'

So I would like to set the php include path so it will resolv开发者_开发知识库e no matter what. Here's what I've tried...

set_include_path(get_include_path() . PATH_SEPARATOR . "../../../");
include 'header.php';

I've also tried setting the path like so...

// get_include_path() returns .:/opt/lampp/lib/php
set_include_path(get_include_path() . PATH_SEPARATOR . "/opt/lampp/public_html");
include 'header.php';

I've never been able to successfully set the include path. What am I doing wrong?

You could try :

include($_SERVER['DOCUMENT_ROOT'] . '/header.php');

Add a call to: http://php.net/manual/en/function.getcwd.php to the same script as

set_include_path(get_include_path() . PATH_SEPARATOR . "/opt/lampp/public_html");

And then adjust "/opt/lampp/public_html" according to the getcwd() output.
