PHP把对象转换成数组

[entities] => Array
(
[0] => stdClass Object
(
[uuid] => bfad2f4a-7954-11e5-b4ff-65f091f822e8
[type] => chatmessage
[created] => 1445584060468
[modified] => 1445584060468
[timestamp] => 1445584059837
[from] => xtmtd
[msg_id] => 120341804573786540
[to] => 1445584043036
[groupId] => 1445584043036
[chat_type] => groupchat
[payload] => stdClass Object
(
[bodies] => Array
(
[0] => stdClass Object
(
[type] => txt
[msg] => ttttt
)

)

)

)
已解决：
function object_to_array($obj){
$_arr = is_object($obj) ? get_object_vars($obj) :$obj;
foreach ($_arr as $key=>$val){
$val = (is_array($val) || is_object($val)) ? $this->object_to_array($val):$val;
$arr[$key] = $val;
}
return $arr;
}

你这种写法更适合想要把私有或者保护的属性取出来。
如果只是公有属性，完全可以使用更方便的做法：
$res = json_decode(json_encode($obj),true);
$obj是原始对象，$res则是数组了。
