打印数组php的值

Question

我有一个值数组

Array (
    [und] => Array (
        [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>
         )
     )
 )
