Question about php objects?

Question

PHP

Good day !
I would like to ask, I can’t understand - no matter where I look, I can’t find about the fact that in the arguments of the called function you can create a function or an object
, the code from cakephp will be given and here I just can’t understand what goes where and where.
I tried to find it and for a month now I can not find the necessary information for myself.
he creates on the go or calls?

Router::scope('/', function ($routes) {
    $routes->connect('/', ['controller' => 'Articles', 'action' => 'index']);
});

How can you explain such a construction - that is, it calls a static method (as I think) and uses the '/' separator in it, then creates a function in which there is also a routes argument and starts calling - that is, assigning the name of the controller (I feel that it is close but I don’t understand how it all works)
Help someone with what they can - well, in a sense - understand

Answer 1

the static method is called with the first parameter of the string type and the second parameter of the callable pseudotype. callable means that this value can be called as a function. the declaration of this function is given when calling, i.e. this most callable-value is initialized. inside the Router::scope static method, this value will be called as a function that takes one parameter and calls its connect(string, array) method
