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']);}
