Does PHP support true multiple inheritance like C++?
Both PHP and C++ are object oriented programming languages that support class inheritance.
There are some differences: C++ supports multiple inheritance, while a PHP class can only have a single base class.
To make up for not having multiple inheritance, PHP supports interfaces and traits..
Why Multiple inheritance is not possible?
A class can implement any number of interfaces but can extend only one class. Multiple inheritance is not supported because it leads to deadly diamond problem. … This primarily consists of operator overloading (although it does have method overloading), multiple inheritance, and extensive automatic coercions.”
How inheritance is implemented in PHP?
Inheritance in OOP = When a class derives from another class. The child class will inherit all the public and protected properties and methods from the parent class. In addition, it can have its own properties and methods. An inherited class is defined by using the extends keyword.
What is PHP trait?
Traits ¶ … 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 parent :: in PHP?
parent:: is the special name for parent class which when used in a member function.To use the parent to call the parent class constructor to initialize the parent class so that the object inherits the class assignment to give a name. NOTE: PHP does not accept parent as the name of a function.
How many types of inheritance are there in PHP?
three typesGenerally, inheritance has three types, single, multiple and multi-level inheritance. But, PHP supports single inheritance and multi-level inheritance. That means the subclass will be derived from a single parent class.
What is inheritance example?
Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents. With inheritance, we can reuse the fields and methods of the existing class. Hence, inheritance facilitates Reusability and is an important concept of OOPs.
Is PHP can support multiple inheritance?
PHP doesn’t support multiple inheritance but by using Interfaces in PHP or using Traits in PHP instead of classes, we can implement it. … Classes, case classes, objects, and traits can all extend no more than one class but can extend multiple traits at the same time.
What is overloading and overriding in PHP?
Method overloading occurs when two or more methods with same method name but different number of parameters in single class. 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.
