How can I use a php array as a path to target a value in another array?

Question

I want to access a specific array\'s property by using a separate array as the path. The problem is the property in question may be at any depth. Here\'s an example...

It's not the greatest code, but should work:

function getValue($pathArray, $data)
{
   $p = $data;
   foreach ($pathArray as $i)
   {
     $p = $p[$i];
   }

   return $p;
}
