PHP function to make slug (URL string)


I want to have a function to create slugs from Unicode strings, e.g. gen_slug('Andrés Cortez') should return andres-cortez. How should I do that?


Solution

  • Instead of a lengthy replace, try this one:

    public static function slugify($text, string $divider = '-')
    {
      // replace non letter or digits by divider
      $text = preg_replace('~[^\pL\d]+~u', $divider, $text);
    
      // transliterate
      $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    
      // remove unwanted characters
      $text = preg_replace('~[^-\w]+~', '', $text);
    
      // trim
      $text = trim($text, $divider);
    
      // remove duplicate divider
      $text = preg_replace('~-+~', $divider, $text);
    
      // lowercase
      $text = strtolower($text);
    
      if (empty($text)) {
        return 'n-a';
      }
    
      return $text;
    }
    

    This was based off the one in Symfony's Jobeet tutorial.
