Try that. You had an extra bracket.
试试那个。你有一个额外的支架。
The error was actually in the line function __construct(). It created a function and then an empty set of brackets (doesn't actually error).
错误实际上是在行中function __construct()。它创建了一个函数，然后创建了一组空括号（实际上并没有错误）。
Then, you never ended up breaking out of the construct function so it error-ed when you tried to use the public parameter inside a function, which is not valid syntax.
然后，您永远不会结束构造函数，因此当您尝试在函数内使用公共参数时它出错了，这是无效的语法。
This is why we make consistent bracket placement, so we always put stuff in the same place, and thus can easily spot mis-placements.
这就是为什么我们保持一致的支架放置，所以我们总是把东西放在同一个地方，因此很容易发现错误的放置。

In other words, you have a syntax error:
换句话说，你有一个语法错误：
function __construct() { <-- note the extra open curly
{ <-- note the extra open curly

I had the same Problem and then i found out that the curly braces "{" of my class was missing .
我遇到了同样的问题，然后我发现我班级的花括号“{”不见了。
