remove characters? 1

[idtstudios2]

I have a bunch of links that are formated like so:

http://soandso.com/tag/monkey/

http://whatever.com/tags/monkey/

Now obviously "monkey" is just an example tag. In reality the tags would nearly always be different. What I need is to be able to pass the link to a function as a string and have the function return only the tag. ex:

pass:

http://blah.com/tags/war/

and get: war

Now, I know how to take individual characters out of a string, but I am at a complete loss on how to remove everything but the tag from such a link?

And ideas or functions out there?
Thanks

this code should do what you want

<?
$url = "[URL unfurl="true"]http://blah.com/tags/war/";[/URL]

echo get_tag($url);

function get_tag($url)
{
	$p_url = parse_url($url);
	if (!empty($p_url['path'])):
		$path = explode ("/", trim ($p_url['path'], "/")); //gets rid of starting and trailing slash then splits the path string into an array separated by the slash
		return ($path[count($path)-1]); // returns the last element of the array
	else:
		die("no path specified in the url");
	endif;
}
?>

Look at using explode() to do this.
