PHP development basics, classes and objects

PHP has perfect support for object-oriented programming. Classes are templates for objects, objects are instances of classes, and namespaces are the ultimate solution to naming conflicts for global members. Starting from PHP5.3, the emergence of namespaces, and PHP.5.4, the Trait class breaks through the limitations of single inheritance, making the functions of the class more flexible.
