语法错误、意外的令牌"<<"、预期"function"或"const"

Question

我在将本地开发环境升级到php8后阅读了这篇文章。

并在我的课堂上实现它，比如：

<<Attribute('foo')>>
public function index()
{
$posts = (new Post)->get()->withMany('image');
return $this->app()->view('index', compact('posts'));
}

并返回错误。

语法错误，意外的令牌"lt<"；，期望"；函数"；或"；const"；

在php8中这样做真正合适的地方是什么。我是不是错过了什么？

Answer 1

PHP 8中正确的属性语法是：

#[Attribute('foo')]

Answer 2

public function create(Request $request)//create object of the request
{ 
$student = new Student;//create object of the model
$student->name = $request->name;
$student->city = $request->city;
$student->marks = $request->marks;
$student->save();
return redirect('index');//if we write this out of the curly braces then this error show

}
