How to take a string after the slash?

Like:

"http://www.blog-name.com/search/taio cruz"

---------------------------------------------^
 "Sorry, no posts were found with the
tag taio cruz"

The Problem:

If the user enters http://www.blog-name.com/search/taio cr开发者_开发技巧uz, the browser will look for a folder named "taio cruz", won't it ?

How can I get the value "Taio Cruz"?

echo basename("http://www.blog-name.com/search/taio cruz"); //taio cruz

$url = 'http://www.blog-name.com/search/taio cruz';
$val = end(explode('/', $url));
// $val is now 'taio cruz'

$url = 'http://www.blog-name.com/search/taio cruz';
$last = substr($url, strrpos($url, '/') + 1);
//$last is now "taio cruz"
