PHP Static Methods

This lesson is part of PHP · All levels

Summary

A static method is a method that is called directly by the class name using the symbol:: without the need to create an object. This method doesn't have $this because it's not tied to a particular instance. Static methods are suitable for utility functions such as validation, calculation, or object-builder.

Key points

Static calling uses the NameClass::.
Static method can't use $this because it runs without an object.
Static method calls another static method with self:: or static::.
