Object Oriented PHP (Lesson 2: Objects & Static Methods)

Twitter Follow


An object is the implementation of a class. As discussed in lesson 1, a class is simply a blue print that outlines something. An object is the actual thing that specifies the specific details.

Objects: Implementation of a Class

  • Conceptualize a band
    • A band has a name
  • A band has members
  • A band can add a member
  • A band has music
  • A band can play music

Static Methods:

  • Are callable from the class level (You don't need to create an instance of the class to call it)
  • Are considered "global to the class namespace"
  • I recommend watching the tutorial linked above to better understand static methods - the screencast does a thorough job explaining static methods.

Objects

In object-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. ... Each object is an instance of a particular class or subclass with the class's own methods or procedures and data variables.

Static Methods

In object-oriented programming (OOP) the methods that belong to a class definition are called static methods. (Sometimes they are called class methods, but this is confusing.) A static method is part of a class definition, but is not part of the objects it creates. Important: A program can execute a static method without first creating an object!
