PHP 数组去重查询

$sh_array = array(); foreach ($data[0] as $ite){ reset($ite); $first=current($ite); array_push($sh_array, $first); } $ch_array = array(); foreach ($data[0] as $item){ reset($item); //指针的使用 current($item); $first=next($item); array_push($ch_array,$first); } //判断导入的数据是非有重复值 if (count($ch_array) != count(array_unique($ch_array))) { return response()->json(['status'=>0,'msg'=>'该导入数组有重复值']); }
