Based on the image provided, code will look this way

echo "<pre>";
print_r($levels);
echo "</pre>";

Check your code for syntax errors

Try this code . i will work.
<?php

    $levels = array(
        1 => array( 'name' => 'level 1', 'desc' => 'This is the first level' ),
        2 => array('name' => 'level 2', 'desc' => 'youve made it to level 2!'),
        3 => array('name' => 'level 3', 'desc' => 'The last level')
      );
      echo"<pre>";
      print_r($levels);
      echo "</pre>";
      ?>
