我一直试图解决这个问题好几个小时。 我觉得它的内容就像if语句应该如何工作一样简单。 贝娄是我试图添加的代码：在代码下面我输入了我试图使用的php：但是我一直在收到有关if语句结构的错误吗？
此外，我相信我的代码本身有问题，因为只有当我插入代码时才会出现此错误。要确认这是伪的： 如果URL中存在sort参数，则在选择表时使用该值。否则使用非订单sql。

我查看了代码，但我无法看到声明中的问题。 PHP告诉我像意外的错误}当我删除它像意外的其他等。
如果您看到任何内容，请分享一些关于此的内容，以及任何一般的结构改进:) 错误代码：解析错误：语法错误，意外＆＃39;}＆＃39;
我还在学习我的批评。

我认为你有一个没有开放if语句的其他人，检查一下（在脚本的最后几行），用你的编辑进行测试并得到相同的
