Yep, I have bought many courses and none of the matches the quality of Gio's content. Still can't believe this is free and Gio doesn't have more engagement on this channel 🤯
100% true. So many tutors bring their character and with that unnecessary fluff into their content. Gio is different. It's just straight and dense knowledge and has just the right amount of his personal opinion in the video(barely any).
These videos are so dense that I really have to take some time to digest the content before moving on to the next one. This is better than any paid course out there so far.
Thank you, appreciate it 🙏. Taking some time & digesting it before moving on is proper way to consume content & learn. Binge watching doesn't work for a lot, may work for some but for me personally never worked, if I binge watch a course I forget it very fast, so I like to take my time with each episode when learning something new
Dude! This was amazing! The fact, that you have covered the topic from all angels was just spectacular. I just came here from another video, that just explained how to implement interfaces, without any context, especially... what damn problem is this utility solving. Thank you!
After watching this video many times, I have finally got an opportunity to use it in one of my projects. I recognized the situation I was about to go into needed an interface to keep the system flexible for the future. I needed to build multiple types of XML requests. Using and interface, I only need one gateway class to pass the different XML request to. Thanks Gio!!
This is another mind opening lesson in my quest to learn PHP. I also think this is the lesson that is now compelling me to go back and look at some of the earlier OOP lessons to really link terms and concepts better. It has certainly started feeling like I'm taking a course in the University. Thanks Gio
You just cleared my doubts and concepts of these topics , which i spent a lot of time searching . Your videos are to the point , with a lot necessary information and with examples . This blew my mind . Kudos to you .
i was always confused about polymorphism that how will it take place and why the hell we needed this to be added in oop basics and today rocky rocked on my polymorphism concept.
So if a class implement an interface that must implement all methods in the related interface. In the another hand, at 15:20, an abstract class implemented an interface but didn't implement the render method in Renderable interface. So abstract classes are exempted from that rule? Thank you so much for lecture.
Abstract classes don't need to implement it, underlying class that extends that abstract class will have to implement it. If you implement it withim abstract class then child classes don't need to implement it. You can't instantiate an abstract class directly.
your video is just awesome. a lot of things i learned from you. i owe you. on thing i want to add in php 8.1 there is may be a new feature default methods in interface . (if i am not wrong )
I think I've already said but I'll repeat: you are the guru for programming. Masterpeace! I"m 2 years in software engineering and I would like to hear your opinion about learning design patterns in OOP: creational, structural, behavioral. How important they are?
Thank you. Design patterns are important but it depends on project & requirements. For some projects you may never use any design patterns. For some you may already be using design patterns without knowing it or without having the fancy name for it. Many devs try to stick design patterns in places where they don't belong, just because they want to use the cool new design pattern they read about someone's blog. I would advise to not do that because I've done that & its not good in the long run. Best thing to do is to understand your requirements & project fully and see what problems you need to solve.
Bro at 5:25 you said constants Defined in intefaces cannot be overridden by the concrete class that implements that interface but in PHP 8.1.0 we can override the constants...just in case someone tries that out on a Newer Version....:D Loving your videos watching them one by one...Your PHP course is the best one on internet....Even a paid course on UDEMY cannot match the concept and effort you have put in your videos...:D
Hey, I have a question. In the video you said that constant defined in the interface can not be overwritten in the class however I am able to do that. Did something change ? Inteface: public const MY_CONSTANT = 1; some Class: public const MY_CONSTANT = 2; or whatever other value This does not throw an error for me.
Yes in php 8.1 it is allowed now, prior to 8.1 it resulted in error. When this video was shot we were using php 8.0. We upgraded to 8.1 soon after and there is a video about 8.1 changes
around 8:59 it sort-of works, but on some random numbers I 'm getting Warnings: Deprecated: Implicit conversion from float 368.5 to int loses precision in \CollectionAgency.php on line 15 Collected $545 out of $737
You are probably on PHP 8.1, during this video we used 8.0 I think, we upgrade to 8.1 later in the series. You can read more info on that here php.watch/versions/8.1/deprecate-implicit-conversion-incompatible-float-string It will trigger warnings when float is implicitly converted to int, so you need to add casting (int) or make sure you pass/use integer
In previously videos you say inheritance cannot inherit multiple inheritance but in course of abstraction you , class field inherit text and boolean and boolean inherit checkbox and radio? before using abstract
@@agahozoclaire9605 PHP doesn't have multiple inheritance support. You can extend a class that extends another class but that's not really multiple inheritance, multiple inheritance would be something like ClassA extends ClassB, ClassC
So if I understand, every time I have the Dependency Injection, that dependency should be an Interface, because if it is a concrete class, that violate to the Liskov principal. Am I correct?
You don't have to have interface all the time. Its better yes to inject any implementation rather than a concrete class, but you also don't want to overdo it. It depends on the app & the type of class you are injecting.
It's phpstorm terminal within the IDE, you just need to connect to your docker container and run commands there. I showed that in Docker lesson beginning of section 2.
You don't have to, but its good to type hint everything, at least in my opinion. It prevents future bugs. You will notice I use strict types in most of my videos & type hint everything. Typehinting to specific class/interface gives you autocomplete features in IDE as well as assurance that no other type is allowed.
It's ok, some of these concepts are not easy to get on first try, it took me some time as well when I was first learning so don't worry if you don't get it right away. You can learn Laravel in parallel, some of the topics in advanced series will help you understand how Laravel works behind the scenes
Because its an abstract class, if you dont define the method in abstract class, you would have to define it in the class that extends that abstract class. You can't instantiate the abstract classes directly
@@ahmedyasser571 In abstract classes you don't have to define the interface methods because its an abstract class, you can't create a new object directly from abstract class, you typically create a new object of some other class that extends your abstract class. That child class that extends your abstract class will need to define the interface methods if its not defined in your abstract class.
It's the same way as accepting arguments as interface. You are returning some implementation of interface. You can return concrete classes as long it implements that interface.
@@rxxt-sh1vj Yes. It works the same way as in arguments. It's polymorphism, you are returning an instance of an interface, so you know that this method call will return some type of instance of that interface without being too specific. Has the same benefits as using polymorphism in arguments.
@@ProgramWithGio Would request you to make a video on interface type hinting that also cover return type of Interface...Thanks for taking the time to reply...I am confused..:D Returning an instance of interface means any class that implements the interface... that class object will be returned..hope that I am correct..:D
@@rxxt-sh1vj Watch this lesson again from 10:00 mark, its the same idea with returns. For example: interface MyInterface {} ClassA implements MyInterface {} ClassB implements MyInterface {} ClassC { public function someFunction(): MyInterface { // this function can now return any implementation of that interface, it can return new ClassA(); // or it can return ClassB return new ClassB(); } }
When you may have multiple implementations of the same contract. For example, if you are implementing a payment processing & want to accept payments. You might want to use Stripe as your processor/gateway. If you code it to an interface and have PaymentProcessor or PaymentGateway interface and implement it inside Stripe class then later if you decide to switch to another provider you could easily create that other class, implement the PaymentGateway interface & most of your other code would continue to function assuming that you coded it right & they are using the interface instead of concrete class.
Hello sir, here is my question abstract class x { protected function x: void protected function y: array protected function z: string private function a: void private function x: void } How can i make an interface for an abstract method..it has no public methods.Assume that abstract class x will be inherited by another class Y which will not be abstract...Can we make an interface for such an abstract class X that has no public methods and only contains protected and private methods??
Bro I have one more ques...Is it necessary that an interface must be used whenever there is polymorphism...I have a class that has 15 public methods with 4-5 private methods...For better organisation of the code and readability of the implemented methods in the class... I want to make an interface and define 15 public methods signature in the interface. Is that a good practice or bad practice according to you..??
Don't overuse the interface. If all those 15 methods are related then yea you can extract them in an interface, however, if some of those methods are not really related then you might want to extract them into multiple interfaces. Also, do you plan on implementing this interface in other classes as well?
@@ProgramWithGio I will not implement any of the interface in other classes...Only one class will implement a single interface in my case...:D Whats your suggestion bro..:D
@@rxxt-sh1vj It's up to you, I personally would not create an interface unless I saw the need to implement it in multiple classes or the need to have polymorphism. No need to overcomplicate things. Also the main deciding factor is if the methods you are planning on putting in an interface are actually related, like if one method processes transaction & other method sends an email then these two are not really related & should not be part of the same interface, you would have two interfaces one called ProcessableInvoice & Mailable interface
@@ProgramWithGio Bro all methods in my interface are interdependent....like I built an orm that has methods like table ...select...where....getSQL(); when all methods are chained it produces a statement like...... select * from users where id = ?. I am building a PHP framework from absolute scratch that will outperform laravel in terms of sheer speed with lowest possible size...It will be under 1 MB in size with less than 150 files and will work with single library developed by me ...the project will not need any other external dependency. My ORM can inject 10,000 records in my sql database in mere 1.64 seconds. If you will compare laravel it has 6700 files approx on just fresh installation. File size is around 32MB which cripples performance on the production server....according to my calculations as the project becomes complex..:D
@@rxxt-sh1vj Got it, they are then related to each other because it's a QueryBuilder essentially, so you could have QueryBuilder interface and if in future you decide to switch from MySQL to something else, you would simply create another driver class and implement that interface

Try to read the same message like you speak in your videos instead editing tip you don't leave any room for breathing your whole video looks like one enormous phrase yes you should cut the spaces of breathing within phrases but yes you absolutely should leave some room for the brain to absorb the information you're providing
Thank you. I improved on this in later videos a little bit & will keep in mind for future as well. It's not just editing, it's just the way I speak :). Need to slow down a bit. RUclips lets you slow it down also & set the playback speed which should help a bit, but I get what you are saying
@@ProgramWithGio Another thing that I found later in the video
In the middle parts you talked about many scenarios, wrote the code for it, but just didn't test it.
If something is relevant, maybe spend 5 more seconds to run the code to show it makes it much easier to understand. Even if you talked what would be the scenario, if you didn't show it, the brain wouldn't grasp the information like it would SEEING it.
It's the same if you give advice to a friend. hehehehe
Thank you, I do try to run it every time to verify that it works, maybe I missed it in few places. Can you give me an example of where I did not run the example code?
