After every lesson I feel lucky to be watching this wonderful course

[aryank]

I am very thankful you make such quality videos. Please keep making more videos on concepts like these, these are very helpful. I really feel like learning a lot in short time watching your videos.

[andersoncdz]

Bro, you are amazing, your php 8 course is incredible, thank you very much for this gem.

[SerhiiDorn]

You make great content. Thank You much. Your code style is highly elegant. I'm looking forward to form request, auth, authorization, middleware, and several most common patterns using in laravel

Thank you for the great content, Gio!

Hi! there is an additional 'i' in entity ! Have enjoyed this course to the fullest, would use it as reference for years to come!!

[stephen.cabreros]

awesome and fantastic. I might gonna use this reference someday. Immutable and side effect free values makes ease by making it less prone to bugs, don't know yet when to use the equalTo method for checking equality. But I might figure it out someday, thanks

Hi Gio, big thanks for these PHP tutorials. I have years of experience, but after these videos, I still learnt a lot and now much more confident.
Btw do you have any recommendations for similar types of videos for Javascript? I have watched Laracasts but looking for something different.

[mohdsyafiqjohar]

Hi, , Thank you for a wonderful video & deep explanation about it.. It's really easy to understand..
May I know, what is the PHPStorm plugin that you using to make this sign '->', '===', etc pretty? I seen it in your another video..

[pusikurac]

do you plan on doing some videos on most common design patterns in php?

I'm really excited about how introducing ORM crippled Entitites into some data-db objects, so you need to introduce things like Value Objects to heal your improper object design. "Entities are normally identified with ID" - yes? Since when? Entity is normal object with properties and methods. Like any other object. Just using ORM made them so. Even senior developers are crippling the OOP by using ORM and then using external "services" to implement methods, which should be integral to object (entity). And then adding artificial IDs to every entity, so no one really understand the code nor DB structure, because is full of IDs you don't really need for anything (because you have composite keys, right?).

To conclude this: you don't need any VO here. Simply use your entities and set their properties by other entities, like dimension etc. Sure, you can make them immutable, by default, or by method. Then your object of PackageDimnension class is valid for whole module, even for another entity, like Pallet. Then pick your pre-set PriceCounter, feed it with Package object and it will set the price. Then just pass the object into some kind of mapper to store value, that's it.

I suggest that you make Laravel course. Thank you

Hi Gio, I enjoyed this video. Learning further to simplify an application and make it easier to manage. But pls, why did we need to create the equalto() function? I didn't quite get that. Why do we need to compare the the other value object with the current value object? I understood the function, its the "why" I didn't get. Thanks a lot Gio.

[hansschuijff]

Valuable lesson again, Gio, . Thank you.

In the code you kept the new enum, VO's and Service class together in a directory. Is that what you would normally do? I can see they are related and perhaps the only relevance for them is in that service, but you also created an enum directory in the app, so I wondered if there are rules in that you follow.

[pasizdobrekuce]

Wow man! This is so so useful. Thank you so much! Please if you have time (and will), make a short series on DDD.

[codingzen]

PHP design patterns stuff would be a nice addition if it's not already planned on the series. Very few resources on this on YT.

[rxxt-shvj]

Please also make a video on building middleware from scratch and its implementation without using any framework

[truthteachers]

In my view, DTO should called as Data Transformation Object as i see it was only doing transformation and not transfer. This is very similar to what we do in Data Warehousing using ETLs. I may be wrong.
