This is something simple that I don't see explained in too many texts. I guess it's just so simple that people should get it right away. This is for the ones that don't...
Basically, use '$this' to get the method (function) working if you want to use it inside another method, but within the same class.
$obj = new Fruitcake;
$obj->Bread();
The resulting output will be: "hello cashews!"
