Question

我有

foreach(["ge","en","ru"] as $lang)
        {
            Tour_trans::create([
                "tour_id" => $tour->id,
                "lang_id" => Langs::where('lang', $lang)->first()->id,
                "title" => $data["" . $lang . "_title"],
                "location" => $data["" . $lang . "_location"],
                "dept_time" => $data["" . $lang . "_dept_time"],
                "depture_time" => $data["" . $lang . "_dept_time"],
                "return_time" => $data["" . $lang . "_return_time"],
                "body" => $data["" . $lang . "_body"],
                "days" => $data["all_days"]->$lang
            ]);
        }

$ data是一个json对象。一切正常，除了最后一行

"days" => $data["all_days"]->$lang

我收到错误类stdClass的对象无法转换为字符串。在$ data [“all_days]中有3个数组对象 - ge，en，ru。所以我想在循环中到达这个属性

这取决于json_decode的第二个参数的选择：

mixed json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )

如果$assoc设置为true，那么您将返回一个关联数组。如果设置为false，则会得到一个对象。

如何在php中使用变量获取对象属性
