Learn about PHP Data Objects (PDO), a database access layer that provides a uniform interface for accessing multiple databases. Know more about this in the blog.
Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a class (called a subclass or derived class) to inherit properties and behaviors from another class (called a superclass or base class). In Python, a subclass can inherit attributes and methods from its superc...
Traits (horizontal reuse/multiple inheritance) are a set of methods, which are structurally similar to a class (but can't be instantiated), that can enable developers to reuse sets of methods freely in several independent classes. Because PHP is a single inheritance language, a subclass can inh...
the original and revised design of C++/CLI. Since neither multiple inheritance nor support of managed templates were provided within the original language design, their continued absence in the revised language could not be conspicuous – except in the paradoxical sense of `your silence is deafeni...
In PHP 5.4 a new feature of the language was added known as Traits. A Trait is kind of like a Mixin in that it allows you to mix Trait classes into an existing class. This means you can reduce code duplication and get the benefits whilst avoiding the problems of multiple inheritance....
Another benefit of using inheritance is that it lets us treat a subclass as if it was a superclass. For example, let's say a program has created multiple instances of the Man and Woman objects. The program might need to call the sleep behavior for all these objects. Because the sleep ...

Multiple inheritance.Derived classes inherit multiple base classes. Instead of this feature, C# introduced base classes without implementation. Such classes are called interfaces in C#. Pointers.While pointers can be used in C#, code that uses pointers has to be marked as “unsafe.” This practice...
Monkey patching is different from inheritance and decorators. Inheritance creates new classes based on existing ones, while decorators modify functions in a more controlled and predictable way. Monkey patching directly alters existing code at runtime. Know more about the key differences and best practic...
