Why is the $_get[[] array here a way of it?

The object in the inside calls the method instead of writing index (), but is written as-$a () Why is that?

Reply to discussion (solution)

$_get[' A ' is a parameter name on the hyperlink, $a = Not $_get, you'll know when you hit $ A.

My question is:
Why not write this $controller->index () here?

but it was written $contrlooer-> $a ()

That's completely fine.

In this case, the URL a can only be equal to index can only adjust the method of index:

A controller is definitely not the only way to index this one.

This is a reference value.
