PHP Classes & Objects Programs

This section contains the PHP solved programs on object-oriented programming approaches such as class & objects, constructor & destructors, various inheritances, interfaces, abstract classes, constants, define, etc. Practice these programs to learn the concept of object-oriented programming approaches in PHP. Each program contains the solved code, output, and explanation.
