Someone please make me to understand, with a small ex, if is possible, how the PHP composition is helping me in the PHP OOP. I looked on tutorials but I didn't understand too much. Even here I searched and most of the topics with the title php composition don't have anything inside about composition. I read about composition in PHP Advance Programming by Larry Ullman, but he only mentioned this subject in the book, in just one proposition. Thank you in advance.
