Answer 1

Instead of using anonymous functions or more complex methods, you can just use one of methods supported for passing callbacks (see the documentation on callbacks):

A method of an instantiated object is passed as an array containing an object at index 0 and the method name at index 1.

To pass "info" method of current object as a callback, just do the following:

array($this, 'info')

and pass it wherever you want to use "info" method as a callback within one of the objects other methods.
