Answer 1

If you have php-intl :

/**
 * Transform (e.g. "Hello World") into a slug (e.g. "hello-world").
 *
 * @param string $string
 *
 * @return string
 */
public function slugify($string)
{
    $rule = 'NFD; [:Nonspacing Mark:] Remove; NFC';
    $transliterator = \Transliterator::create($rule);
    $string = $transliterator->transliterate($string);

    return preg_replace(
        '/[^a-z0-9]/',
        '-',
        strtolower(trim(strip_tags($string)))
    );
}

Otherwise, have a look on the doctrine extensions

Use either l3ppard's sluggable extension ( GitHub repository) ...

... or KnpLabs sluggable behavior ( GitHub repository ).
