> _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](https://cleancode.studio/series/object-oriented-php/episodes/2): Implementation of a [Class](https://cleancode.studio/series/object-oriented-php/episodes/1)
- 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](https://cleancode.studio/series/object-oriented-php/episodes/2):
- 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!
