How Does PHP's Late Static Binding Differ from Standard Inheritance?

An Exploration into PHP's Late Static Bindings

PHP introduces the concept of late static bindings, a nuanced feature that enhances object-oriented programming. Unlike regular inheritance rules, the "self" keyword under late static binding does not adhere to the expected behavior. Specifically, "self" always represents the current class, regardless of calling context.

To address this limitation, PHP employs the "static" keyword for late static binding. Unlike "self," "static" resolves to the class in which it was first utilized, effectively binding to the class at runtime.

To delve into the intricacies of late static bindings further, it's highly recommended to explore the PHP manual's thorough documentation. While the gist of it has been presented here, grasping the nuances of how "self," "parent," and "static" interact within this context requires a detailed study of the manual's examples. This will illuminate the subtle yet significant differences in their behavior under late static bindings.
