如何将$ array [x [y]]更改为$ array [x] [y]

How to change the array:

$array['db[blabla]']

to this array:

$array['db']['blabla']

Thanks.

Here is my crack at it (tested)

$array['db[blabla]'] = 10;
$newArr = array();
foreach($array as $key => $value) {
    $r = explode("[",$key);
    $newArr[$r[0]][str_replace(']', '', $r[1])] = $value;
}
