urldecode - Output a part of URL in php -

 http://example.com/name/first_name/last_name/john%2c+smith 

what php code output last part of url?

so, becomes "john, smith".

thank much.

edit:

i realized url ended / , answers given below not pick up. change should make?

http://example.com/name/first_name/last_name/john%2c+smith/ 

edit 2:

so, link dynamically generated following:

href="http://example.com/name/first_name/last_name/<?php echo $full_name ?>" 

you can use parse_url second parameter php_url_path

$url = urldecode("http://example.com/name/first_name/last_name/john%2c+smith"); $arr = array_filter(explode('/',parse_url($url, php_url_path))); print_r(end($arr));

as per requirement dynamic url can use

$url = urldecode("http://$_server[http_host]$_server[request_uri]");
