PHP Abstract Classes & Methods - Full PHP 8 Tutorial

In the previous lesson we covered inheritance, in this video, you'll learn about abstract classes & abstract methods. Abstract classes use inheritance so if you have not watched the last lesson about inheritance please make sure to watch that first since the same rules apply to abstract classes.

***SUMMARY***
- Abstract class is the class that has at least one an abstract method
- Abstract class does just declare the abstract method but does not implement it. In other terms, it knows what of the abstract method but not how of the abstract method
- Child class method knows how the abstract method
- Rule for using the abstract method:
-. The signature of the abstract method and child class method must be the same however the abstract method can have additional arguments.

Thank you, @Gio! I now grasp the concept of abstract classes better than I did in college.

[Zubbee]

Great lesson. I'm really counting on more exposure. To really know when to implement abstract classes or not. This is technical stuff man. Thanks Gio

Hi sir
everything is just perfect and up to the mark.
just one suggestion as most of us make notes it will be very helpful if imp point you mention in between could be available as summary in one frame so that we can take snap of it rather than typing by our self.

Again thanks for what u r doing GBU🙂🙏.

Thanks, well explained.
What is the major difference between Abstract and Interface?

[Armando-pxhi]

Thank you so much Gio, I said and will keep saying that you are the best who knows everything about PHP. I have one question, is open-closed principle often used in oop or not so?

[mocwgoc]

I think that abstract class can also be used as a kind of documentation that is embedded directly in the code instead of writing it as comments on the code

[josephjohn]

why do we need to create instances of Field and Boolean and display them if we don't need them? we can as well ignore creating the instances and display the rest? i need explanation on this, thanks

[agahozoclaire]

can abstract class inherint another class as an abstract ? and another thing you say about override default values the render function in the parent class has argument which is $name.?
