php 数组的防止重复,key value的用法,拼接,拆分的用法

??????? foreach($a as $key=>$val){//key 为数组$a 下标?? $val为$a的值
??????????? $val = array_unique($val);//这个是防止数组$val重复的
??????????? $insertDate = array(//设置新的数组
??????????????? 'ini_id' => $key,//数组下标'ini_id'
??????????????? 'door_id'=>implode(',',$val)//拼接$a数组的值? explode是拆分
??????????? );
