SEO url string filter Using PHP

[Kevin]

This function will transform any string to an seo url like string. It suports latin, french and german special characters.

Example: applying the function to "Exemplo de aplicação da função" returns "exemplo-de-aplicacao-da-funcao"

    <?php
     
        function seoUrl($str){
            /** by Jonatas Urias B Teixeira    **/
            $a = array('/(à|á|â|ã|ä|å|æ)/','/(è|é|ê|ë)/','/(ì|í|î|ï)/','/(ð|ò|ó|ô|õ|ö|ø|œ)/','/(ù|ú|û|ü)/','/ç/','/þ/','/ñ/','/ß/','/(ý|ÿ)/','/(=|\+|\/|\\\|\.|\'|\_|\\n| |\(|\))/','/[^a-z0-9_ -]/s','/-{2,}/s');
            $b = array('a','e','i','o','u','c','d','n','ss','y','-','','-');
            return trim(preg_replace($a, $b, strtolower($str)),'-');
        }
     
    ?>
