PHP OOP Static Properties

 PHP OOP – Static Properties

•  Shared by all objects
•  Accessed using ClassName::$property 
•  Declared with static keyword

 Basic Static Property Example

You don’t need to create an object.

 Access Static Property Inside Class

Use self::$property inside the same class.

 Modify Static Property

All Objects Share Same Static Property

All objects update one shared variable.

 Static Property with Inheritance

Child class inherits static properties.

  Override Static Property in Child

Each class keeps its own version.

  Late Static Binding with Static Properties

Use static::$property for overriding behavior.

 Wrong: Cannot Use $this with Static Property

Because $this refers to an object, not the class.

  Practical Use Case – Configuration

  Practical Use Case – Auto Incrementing ID
