php call array from string

Question

I have a string that contains elements from array.

$str = \'[some][string]\';
$array = array();

How can I get the value of $array[\'some\

Answer 1

I think regexp should do the trick better:

$array['some']['string'] = 'test';
$str = '[some][string]';
if (preg_match('/\[(?\w+)\]\[(?\w+)\]/', $str, $keys))
{
    if (isset($array[$keys['key1']][$keys['key2']]))
         echo $array[$keys['key1']][$keys['key2']]; // do what you need
}

But I would think twice before dealing with arrays your way :D
