In your example, $controlleris a PHP object created somewhere, and permissionCheck is a function defined in that object that is being called with the variable $retbeing passed to it. Check this: Reference - What does this symbol mean in PHP?.
在您的示例中，$controller是在某处创建的 PHP 对象，permissionCheck 是在该对象中定义的函数，该函数$ret正在通过传递给它的变量进行调用。检查这个：参考 - 这个符号在 PHP 中是什么意思？.

It's used to address a function or property of a class. In this case a function of the controller class seems to be called.
它用于寻址类的函数或属性。在这种情况下，似乎调用了控制器类的函数。

Operator ->is for access to the non-static members of $controllerobject. In your case, the member is the function permissionCheck.
运算符->用于访问$controller对象的非静态成员。在您的情况下，成员是 function permissionCheck。
