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...

Answer 1

Here is a different approach:

while($d = array_shift($path))
    $data = $data[$d];

Answer 2

A simple loop should work:

Update: sorry did check my code

foreach($path as $id) 
{
    $data = $data[$id];
}

echo $data;

Result:

deeper_value

This will overwrite the $data array so you might want to make a copy of $data first like David did in his example.

Answer 3

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

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

   return $p;
}
