How to get the last path in a URL?

Question

I would like get the last path segment in a URL:

• http://blabla/bla/wce/news.php or
• http://blabla/blablabla/dut2a/news.php

For example, in these two URLs, I want to get the path segment: 'wce', and 'dut2a'.

I tried to use $_SERVER['REQUEST_URI'], but I get the whole URL path.

Answer 1

Try:

$url = 'http://blabla/blablabla/dut2a/news.php'; $tokens = explode('/', $url); echo $tokens[sizeof($tokens)-2]; 

Assuming $tokens has at least 2 elements.

Answer 2

Try this:

function getLastPathSegment($url) {     $path = parse_url($url, PHP_URL_PATH); // to get the path from a whole URL     $pathTrimmed = trim($path, '/'); // normalise with no leading or trailing slash     $pathTokens = explode('/', $pathTrimmed); // get segments delimited by a slash      if (substr($path, -1) !== '/') {         array_pop($pathTokens);     }     return end($pathTokens); // get the last segment }      echo getLastPathSegment($_SERVER['REQUEST_URI']); 

I've also tested it with a few URLs from the comments. I'm going to have to assume that all paths end with a slash, because I can not identify if /bob is a directory or a file. This will assume it is a file unless it has a trailing slash too.

echo getLastPathSegment('http://server.com/bla/wce/news.php'); // wce  echo getLastPathSegment('http://server.com/bla/wce/'); // wce  echo getLastPathSegment('http://server.com/bla/wce'); // bla
