PHP does not support method overloading. Method overriding means two methods with same method name and same number of parameters in two different classes means parent class and child class.
Is method overloading supported by PHP?
PHP does not support method overloading. In case you’ve never heard of method overloading, it means that the language can pick a method based on which parameters you’re using to call it. This is possible in many other programming languages like Java, C++.
What is method overriding in PHP?
Introduction to the PHP overriding method
Method overriding allows a child class to provide a specific implementation of a method already provided by its parent class. To override a method, you redefine that method in the child class with the same name, parameters, and return type.
What method prevent overriding in PHP?
The final keyword prevents child classes from overriding a method by prefixing the definition with final . If the class itself is being defined final then it cannot be extended. Note: Properties and constants cannot be declared final, only classes and methods may be declared as final. As of PHP 8.0.
What languages support method overloading?

What is PHP trait?
Traits are a mechanism for code reuse in single inheritance languages such as PHP. A Trait is intended to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies.
What is static and final in PHP?
final , as mentioned before can be used along with any method or class definitions and hence; applicable with all of them. static can not be applied to class definitions but can be used for class properties. UPDATE. modifiers are allowed for class constants since PHP 7.1. 0.
