Generating doctrine slugs manually

Question

I\'m using sluggable behavior in my Symfony2 project, but now I would like to make many slugs for one page, based on different texts (current title, old title(s), users text

Answer 1

I found solution by accident here. Code:

use Gedmo\Sluggable\Util as Sluggable;    

$string = 'My own text!';
$slug = Sluggable\Urlizer::urlize($string, '-');
    if(empty($slug)) // if $string is like '=))' or 'トライアングル・サービス' an empty slug will be returned, that causes troubles and throws no exception
        echo 'error, empty slug!!!';
    else
        echo $slug;
