Question

由于我是PhP的新手，遇到了5个我似乎无法弄清的错误，这非常令人困惑，这是为了做作业，但是我做了很多事情，我只需要弄清楚问题所在就可以评论代码与代码有关

问题被评论

我试图解决语法问题并最终破坏了一切，所以我又回到了原来的状态

这只是不编译，而这正是我真正需要做的，我仍然认为我的语法和问题只是错误的地方。任何帮助表示赞赏。

编辑我的if语句将运行，但是我得到的错误最终是 This is after changing the code but leaving is set as ($_POST["btnCalc"]))

Answer 1

1和2应该为$ _Post [“”]（双引号）。 3你想念一个;回声之后。 4 $ rowRemainder未设置为等于任何值。

代码问题不起作用，不确定我的语法是否关闭或缺少任何内容
