Question

This sounds confusing but isn’t. Here is the problem:

1. application is hosted at http://www.site.com/app
2. in /app, there’s a htaccess rerouting any non-existing files or directories to index.php
3. index.php does $method = end(explode('/',$_SERVER['REQUEST_URI'])); and calls it method
4. now, method could be CSS, so CSS routine needs to take the css file and replace any url(images/ with url(http://site.com/app/images

The problem is “guessing” http://site.com/app/images, because REQUEST_URI can range anywhere from the cleanest site.com/images and up to the dirtiest http://ex.gau.mit.edu/~jonas/site/projects/2012/app/ignoredmethod/more/ignored/methods/css

Without specifying the script URL, how can I guess the images folder URL?

Answer 1

SCRIPT_NAME will be really useful here.

define('URL', (dirname($_SERVER['SCRIPT_NAME'])) == "/" ? "" : (dirname($_SERVER['SCRIPT_NAME']))); 

Usage:

echo "<a href='http://$_SERVER[SERVER_NAME]/".URL."/images/image.jpg'>image</a>";
