Question

我要过滤某些条件下的数组。

我正在为我的旅行门户网站随机生成一组酒店，其中，基于位置的酒店的所有排列都应该出现。

条件是：- 1.在2个连续的夜晚中，在相同位置的夜晚只能获得相同的酒店和房型。

我的方法（我正在使用array_filter（））：

public static function my_function($item_values)
{
    for($i=0;$i<count($item_values);$i++){

        if($i>0){
            $j = $i-1;
            $preData = explode('-',$item_values[$j]);
            $data = explode('-',$item_values[$i]);
            if($data[0] == $preData[0]){
                if($data[1] == $preData[1]){
                    if($data[2] == $preData[2]){
                        return TRUE;
                    } else {
                        return FALSE;
                    }
                } else {
                    return FALSE;
                }
            } else {
                return FALSE;
            }
        } else {
        return true;
        }
    }
}

我的数组：

因此，在数组元素[1] => 1-100-269中表示为：

[1] ==键和夜晚。 1是位置ID。酒店ID为100 房间类型ID 269。

我希望在不同的夜晚，同一地点的阵列酒店和房间类型相同。但是我得到了所有323个数组元素。

感谢您的帮助。
