PHP Stack brings a stack data structure to PHP. It allows developers to utilize Push, Pop, Search, Empty (a check if the stack is empty), Size and "Peek". Peek allows developers to look at the top item in the stack without Popping it from the stack.
Basically, a Stack is a data structure more commonly found in lower level programming languages. It is useful for wanting to organize data in a First In Last Out fashion. This project is released under GPL v3.
