  • This course assumes that you have PHP basics knowledge or taken few beginners courses external or including on our website blog.
  • You should know atleast how to run PHP code on your computer.

Why should I learn OOP?

Object Oriented Programming (OOP) is programming concept which brings the following advantages to this course:

  • You logical group your code into Components.
  • You build Small Components of code which can be reused.
  • Components are extend or leverage from other Components.
  • Simplify the complex concept into smaller Components.
  • Extending the component, Reusing the Component, Hiding Features and many other benefits.

If you want to be senior developer or build website for business then you should know how to write in OOP.

Even when you use the 3rd Party Libraries they are built using OOP and without knowing this OOP it is really difficult to use 3rd Party Libraries as well.

Building your projects using OOP will be easy to extend and share by other developers as well.

How this course can help me learn OOP?
