Problem with this is that it places restrictions on where the mixin method can be used, and forces the class doing the ...

I am new to PHP and programming in general. I have been working on a few things with PHP that have required me to create classes, which has been fine, except that I can't seem to get my class methods to work on arrays that are properties of the class.
