Java URLConnection for PHP$_Getfor MySQL方法

Question

好吧，这有什么问题吗。我试着使用MySQL JConnector for Java，人们说不要，因为它可以包含小程序的详细信息，所以我告诉他们我会使用PHP脚本使用PHP$_GET方法URL。他们说会没事的。然而，我发现有两个问题

1.）他们很慢。URL连接至少需要4-5秒。即使我把它指向localhost

2.）有很多代码。也许我只是做错了

这就是我所拥有的——有效

以下是回应：

Let's change the level!
You're Lvl is: 123456
Trying to update level...
You're NEW Lvl is: 777
Level update done!

它可以工作，但速度慢且体积大——我该如何解决这个问题
