php - recreate array from flat to multidimensional?

[Ollie]

I am trying to take a flat array and recreate it so that it's multidimensional. I've been looking into array_combine and array_merge, but I'm not sure that either of those will give me what I'm hoping for... The array, in it's current form (and this is just a simplified example):\[code\]Array( [0] => stdClass Object ( [tid] => 31 [name] => Safeway [parents] => Array ( [0] => 0 ) ) [1] => stdClass Object ( [tid] => 32 [name] => Dairy [parents] => Array ( [0] => 31 ) ) [2] => stdClass Object ( [tid] => 33 [name] => Milk [parents] => Array ( [0] => 32 ) ))\[/code\]I'm trying to create a multidimensional array where each object is a subarray of it's parent. So, in the example above, I'm trying to output:\[code\]Array( [0] => stdClass Object ( [tid] => 31 [name] => Safeway [children] => Array ( [tid] => 32 [name] => Dairy [children] => Array ( [tid] => 33 [name] => Milk ) ) ))\[/code\]
