Question

我尝试将数据从Firebase导入MySQL数据库。

我的Firebase数据如下所示：

现在，我尝试获取此记录并保存到MySQL：

$model = new DbModel();
$wpath = "/messages/". $id;
$wvalue = $firebase->get($wpath);

$wjson = json_decode($wvalue, true);            
$model->message = $wjson["message"]; //this is ok, if I print it'll show the emoji
$model->save();

保存模型后，我在我的数据库中得到了这个：

I'm going to dance ????

我在表格中为我的列设置了utf8mb4_general_ci排序规则，当我通过脚本或用户界面手动插入相同的文字时，似乎工作，但是当我输入时，表情符号不会保存通过php保存我的模型。

我的服务器版本：10.1.16-MariaDB - mariadb.org binary distribution

网络服务器：Apache/2.4.23 (Win32) OpenSSL/1.0.2h PHP/7.0.9

任何建议都将受到高度赞赏。
