php object怎么转成array

/* $object  object对象 数据信息
object(stdClass)#51 (4) {
  ["Message"] => string(2) "OK"
  ["RequestId"] => string(36) "4F15BC21-8548-4692-BC99-23ACF6A53ECB"
  ["BizId"] => string(20) "271812694197084716^0"
  ["Code"] => string(2) "OK"
}
*/
$array = (array)$object;  //核心代码
dump($array);
/* $array 数组  结果信息
array(4) {
  ["Message"] => string(2) "OK"
  ["RequestId"] => string(36) "B5D69728-FAF4-4C64-929D-B8A565CF44CB"
  ["BizId"] => string(20) "150010594197885250^0"
  ["Code"] => string(2) "OK"
}
