Question

Why isn’t the query string added to the GET array when using clean urls? Eg. Using /foo/bar?stack=overflow and the $_GET['stack'] variable is empty.

I’m implementing clean urls with this code:

$request = rawurldecode($_SERVER['REQUEST_URI']);

// Extracts the index.php file path (eg. /my_app)
// There is no need to specify the path to index.php as the script handles it
$path_to_index = str_ireplace($_SERVER['DOCUMENT_ROOT'].'/', '', $_SERVER['SCRIPT_FILENAME']);
$path_to_index = str_ireplace('/'.basename($_SERVER['SCRIPT_FILENAME']), '', $path_to_index);

    // Get rid of the path to index.php
$request = str_ireplace($path_to_index, '', $request);

// Get rid of index.php in the URL
$request = str_ireplace(basename($_SERVER['SCRIPT_FILENAME']), '', $request);

// Our URL is now clean so we can explode
$request = explode('/', $request);

// Delete empty and reindex
$request = array_values(array_filter($request));

If using RewriteRules in a .htaccess

At the end of your RewriteRule line put [QSA] like this:

RewriteRule (.*) index.php?stuff=$1 [QSA]

QSA flag info: http://httpd.apache.org/docs/2.2/rewrite/flags.html#flag_qsa
