     [0] => Array (
      [value] => 
Drupal Development 
PHP 
CSS 
MySql 
Photoshop 
Illustrator 
InDesign 
      [format] => 
      [safe_value] => <li class="drupal">Drupal Development</li> <li class="php">PHP</li> <li class="css">CSS</li> <li class="mysql">MySql</li> <li class="ps">Photoshop</li> <li class="il">Illustrator</li> <li class="in">InDesign</li>
