Answer
Static methods belong to the class and do not need an instance. Non-static methods operate on object properties. Static overuse reduces flexibility.
Quick Answer
Static methods and properties belong to the class itself, not instances. Call with ClassName::method(). No dollar-this available. Non-static methods belong to objects and have access to instance state via dollar-this. Static is useful for utilities, factories, and shared state. Avoid static for anything that needs testing since it creates hidden global state and cannot be mocked easily.
