I'm still suggesting you to loop using fetch() method. Otherwise, you can use array_reduce() to iterate over the array. A sample on codepad is here.

The code(in human readable form) will be:

    $temp2 = $temp['id']; 
    unset($temp['id']); 
    $returnArray[$temp2] = $temp; 
    return $returnArray;
  }
);
