This PHP OOP series helps you master Object-oriented Programming in PHP.<\/p>\n\n\n\n
PHP introduced object-oriented programming features since version 5.0. Object-Oriented programming is one of the most popular programming paradigms based on the concept of objects and classes.<\/p>\n\n\n\n
PHP OOP allows you to structure a complex application into a simpler and more maintainable structure.<\/p>\n\n\n\n
