Better var_dump for Arrays

PrintArray.php

function PrintArray($aVals)
{
   echo "<ul>"; 
   foreach($aVals as $key => $val) 
   { 
      if(is_array($val)) 
      { 
         echo "<li><strong>{$key}</strong>";
         PrintArray($val); 
         echo "</li>"; 
      } 
      else 
      {
         echo "<li>{$key}: {$val}</li>";
      }
   }
   echo "</ul>";
}
