问题：我想要的是一个数组的pid，存不存在第二个数组里，如果少了或者多了就返回个错误。如果都有的话，第一个数组的id是第二个数组的childer的id，如果他们相等的话，将第二数组的其余的childer都去掉只保留相等的；
数组1：
Array
(
[0] => Array
(
[pid] => 47
[id] => 48
)
[1] => Array
(
[pid] => 52
[id] => 54
)

(
[pid] => 55
[id] => 56
)
[3] => Array
(
[pid] => 58
[id] => 60
)
[4] => Array
(
[pid] => 63
[id] => 65
)
)
