Extract part from URL for a query string - php

Question

I need a certain part of a URL extracted.
Example:
http://www.domain.com/blog/entry-title/?standalone=1 is the given URL.
blog/entry-title should be extracted.
However, the extraction should also work with http://www.domain.com/index.php/blog/[…]as the given URL.
This code is for a Content Management System.
What I've already come up with is this:
function getPathUrl() {
$folder = explode('/', $_SERVER['SCRIPT_NAME']);
$script_filename = pathinfo($_SERVER['SCRIPT_NAME']); // supposed to be 'index.php'
$request = explode('/', $_SERVER['REQUEST_URI']);
// first element is always ""
array_shift($folder);
array_shift($request);
// now it's only the request url. filtered out containing folders and 'index.php'.
$final_request = array_diff($request, array_intersect($folder, $request));
// the indexes are mangled up in a strange way. turn 'em back
$final_request = array_values($final_request);
// remove empty elements in array (caused by superfluent slashes, for instance)
array_clean($final_request);
// make a string out of the array
$final_request = implode('/', $final_request);
if ($_SERVER['QUERY_STRING'] || substr($final_request, -1) == '?') {
$final_request = substr($final_request, 0, - strlen($_SERVER['QUERY_STRING']) - 1);
}
return $final_request;
}
However, this code does not take care of the arguments at the end of the URL (like ?standalone=1). It works for anchors (#read-more), though.
Thanks a ton guys and have fun twisting your brains. Maybe we can do this shit with a regular expression.

Answer 1

There's many examples and info for what you want at:

Answer 2

That should do what you need:
<?php
function getPath($url)
{
$path = parse_url($url,PHP_URL_PATH);
$lastSlash = strrpos($path,"/");
return substr($path,1,$lastSlash-1);
}
echo getPath("http://www.domain.com/blog/entry-title/?standalone=1");
?>
