but i cant menaged to do that..

Out put from

!its's SO funny! Blockquote

!its's-SO-funny!

Im trying to get

Why re-invent the wheel? There's a billion tiny libraries to do this. [Here](http://cubiq.org/the-perfect-php-clean-url-generator) is a version that's smaller than yours and work fine with UTF-8. Alternately, [this thread](http://stackoverflow.com/questions/2955251/php-function-to-make-slug-url-string) on SO contain a fine function as well. — h2ooooooo, Feb 18 '14 at 20:01

If you just want to get from

!its's-SO-funny! to itss-so-funny

You can just do something like this before returning:

$final = strtolower(preg_replace('/[^0-9a-zA-Z-]/','',$final));

It removes all characters except those which are alphanumeric or the symbol - and makes everything lowercase.
