[@rosarioveneruso9928]

I can't understand the destruct method thing, about the three examples: In the first case 15:16 "...it will first call the destruct and then print the amount...", then you say that after "applyDiscount" there is no more reference, what do we mean exactly with reference? $amount->getAMount isn't still a reference to the object? The second case we still have a reference in the end so it first prints the amount and then it calls the destruct so it is consistent to me. Last case it seems the same of the first: 1) $amount = ( new Transaction(100, 'Transaction 1')) ->addTax(8) ->applyDiscount(10) ->getAmount(); // isn't like $amount->getAmount? var_dump($amount); // Destruct - amount 3) $transaction = ( new Transaction(100, 'Transaction 1')) ->addTax(8) ->applyDiscount(10); $amount = $transaction->getAmount(); var_dump($amount); // amount - Destruct

[@ProgramWithGio]

Destruct is called when nothing else is referencing the object. At 15:16 that object is only used in that spot so destruct is called before vardump. Try it out and play with it on your local and you'll get it

[@rosarioveneruso9928]

@@ProgramWithGio If I got it well in the first case the getAmount method is already called (with vardamp we only display the value returned) so we have no more reference while in the last case we still have to call the method so there is still a reference to the object.

@@rosarioveneruso9928 Yup exactly

[@rudrakshigupta2965]

@@ProgramWithGio I don't get the last case as --> $transaction = ( new Transaction(100, 'Transaction 1')) ->addTax(8) ->applyDiscount(10); $amount = $transaction->getAmount(); ----------------------------------------------------->refrence ends here var_dump($amount); // amount - Destruct as refrence ends befor var_dump why doesn't it execute destruct before var_dump like that of 1st case???

[@yahelabraham9821]

hii, i have a question, why accessing private properties of an object is not allowed, yet if i var_dump the object, i can see its private properties and their values?

[@ProgramWithGio]

That's the point of private properties, it can't be accessed outside. Var dump is sort of internal function and used for debugging

[@sarc143]

can i ask why type-hinting is recommended? is it for code readability or another reason?

[@ProgramWithGio]

Less prone to type related bugs. Easier to understand and maintain. Makes code a bit predictable while without typed you are forced to add some type check validations.

I am battling with my brain to understand classes and objects, can we use facebook for exampley and can we say that a class is homepage , and it's object is a post?

[@ProgramWithGio]

Here is a simpler analogy. A Car is a class, a specific car (BMW) is an object of the Car class. A Person is a class, Kemal Gogic is an object of that class. Class is kind of like a blueprint where you create objects from

[@kemalgogic595]

[@gedasgedas1720]

Is there any use for stdClass and object casting?

[@ProgramWithGio]

It is sometimes used as DTO (Data Transfer Object) and some API SDKs return objects of stdClass which you can easily convert to an array by casting. I don't think I ever had a good usecase specifically for stdClass.

[@pat1938]

Hey Gio, I don't know why but I get this "Fatal error: Uncaught Error: Typed property Transaction::$description must not be accessed before initialization in /var/www/public/index.php:7 Stack trace: #0 {main} thrown in /var/www/public/index.php on line 7" error and my code looks 1:1 to yours. Timestamp is "Class constructor, $this & constructor arguments" section. If I just var_dump whole $transaction I get "object(Transaction)#1 (2) { ["amount"]=> uninitialized(float) ["description"]=> uninitialized(string) ["1.5"]=> float(1.5) ["test"]=> string(4) "test" }" So it looks like the app is still holding one uninitialized $amount and $description despite the fact I create an object and pass arguments. Do you have any idea why that could be?

[@ProgramWithGio]

Hey, that's because the properties are in un-initialized state until you set it to a value. It can be set in constructor or via default value or setter. You can make it nullable by adding ? to type hinting or simply set the default value to something

[@pat1938]

@@ProgramWithGio Thank you for a such prompt reply! I see, it indeed works now after either setting initial value or adding "?". Could you briefly explain why did it work in your code though (as in the video) without doing these things? btw this course is really golden, i'm impressed and really apprieciate you not only scratching the surface but diving deeply into php, I finally feel that I'll have some valuable skills and knowledge after completing it and not only being stuck at this "foundation" type of knowledge which is basically just like knowing some basics but not really enough to solve any real-scenario problems. Thank you!

[@ProgramWithGio]

@@pat1938 thank you. I briefly explained it from 4:51 to about 10:00 mark. You can see example of that error message there. It worked in my case because I initialized the value in constructor and before that I had it set to default value.

[@pat1938]

@@ProgramWithGio I had the contructor method and I just found out what the problem was.. basically I added $ sign before first amount and description and it caused the whole function not to work properly. So it looked like "$this->$amount = $amount;" instead of "$this->amount = $amount;" I'm not even sure why I did this. Maybe someone will run into the same mistake and find this comment. Thank you again Gio and have a good day:)

[@evilservo]

I only picked PHP because of this tutorial , YES i was thinking of going with python I am good with JS but there was not a single tutorial this massive on any language so i choose php only because of your tutorial my question here is , why return type is set to class , even if we dont specify a return type ( on addTax and addDiscount) we can return instance of object by simply returning $this or this is because of strict type that we do have to mention the return type

[@ProgramWithGio]

That's awesome, thank you & welcome. You don't have to specify return types, I just prefer to always have return types specified so that if wrong type is returned for whatever reason it errors out

[@evilservo]

[@truthteachers]

@@ProgramWithGio 1-30 does not cover the resource type fully. I that video you mentioned you will cover later. But in this video you say have already covered resources. Perhaps what you meant was it covered the type but not the functions related to resource types. Will i be correct in my understanding?

[@ProgramWithGio]

@@truthteachers not sure what you mean. In that video we covered what resource data type is, what functions are you referring to related to resources? I couldn't cover all resource related functions in that lesson because they are different topics if that's what you mean, we just covered the resource data type and file system related functions.

[@truthteachers]

@@ProgramWithGio Ah ok. I checked the php manual. The functions related resources are huge. Thank you for the feedback. Appreciated.

[@ProgramWithGio]

@@truthteachers yup, those functions are all related to their own topics, it's not like array functions, different resource functions work for different things.

[@siyahkedilucifer]

Additional information for construct magic method; after the php 8.0 and later, you could use constructor promotion. Instead of; protected int $amount; public function __construct(int $amount) You could just use this short-hand public function __construct(protected int $amount)

Yup, we cover that in the next video

OOP is so painful to learn that I kind of want to just a framework just to abstract/automate it all away for me lol.

@@ProgramWithGio I think it's got to be that way though i.e. specialize in a framework to get a job. Web dev is just too much otherwise (the process of creating a site from scratch is so overengineered and excessively complex and in any case you might have to relearn everything if your next employer uses different frameworks)

Trying to learn all this from scratch just causes me enormous frustration.

[@ProgramWithGio]

@@illegalsmirf I totally understand, for such websites you could use templates, or purchase a theme.

He's not iterating over the same thing many times in different ways, he starts simple and is expanding the complexity of the subject to provide a comprehensive and deep understanding. These are not tutorials, these are lessons.

[@ProgramWithGio]

My goal was not to rush through the course and have a "Learn PHP in 2 hours crash course". My goal was to start simple and dig deeper & expand as @neozes explained.
