PHP rename array keys in multidimensional array

Question

In an array such as the one below, how could I rename "fee_id" to "id"?

Array (     [0] => Array         (             [fee_id] => 15             [fee_amount] => 308.5             [year] => 2009                         )      [1] => Array         (             [fee_id] => 14             [fee_amount] => 308.5             [year] => 2009          )  ) 

Answer 1

foreach ( $array as $k=>$v ) {   $array[$k] ['id'] = $array[$k] ['fee_id'];   unset($array[$k]['fee_id']); } 

This should work
