How to create URL slug with translation from a string in PHP

 

This is what i use, this function also translates various accent characters.

function createUrl($string = '') {
        
        $chars = array(
            // Decompositions for Latin-1 Supplement
            chr(195).chr(128) => 'A', chr(195).chr(129) => 'A',
            chr(195).chr(130) => 'A', chr(195).chr(131) => 'A',
            chr(195).chr(132) => 'A', chr(195).chr(133) => 'A',
