problemas com a função slug.

gedmilson · Dezembro 7, 2015

Estou com a função de slug quase terminada só está faltando fazer a separação por traço.

Tem com vocês darem uma olhadinha no codigo e me dizer o que está errado?

<?php

//Remove a acentuaçao grafica

function remove_accents($string) {

if (!preg_match('/[\x80-\xff]/', $string))

return $string;

if (seems_utf8($string)) {

Cara deu tudo certo era só uma linha de código que eu tinha esquecido de fazer no slug vou mandar o código resolvido para eventuais necessidades. Valeu pela a sua ajuda ela foi crucial para resolver esse problema.
