I was planning on buying a PHP course on udemy because I want to enhance my php knowledge. I'm a laravel developer and I feel like I already forgot the most part of pure php. I'm glad I found this series, and its FREE!! Thank you!

[@ProgramWithGio]

Happy to hear, thank you 💙

[@hansschuijff]

A more difficult subject to get into, since the php doc itself that you showed at the start of the video, is not very explanatory or clear about what attributes are and how they work. After seeing this lesson through and making the effort to code along with you I am now confident that I understand it enough to be able to use it. What made it clear for was that you showed that Attribute is just another class you can use and extend by creating your own Attribute classes. In the end it didn't seem difficult anymore and that shows me you're a great teacher. Thanks, Gio. Top job.

Wow, this one was pretty cool. I'm like seeing how we are advancing and yet you always seem to say that it can't be used in production... and I'm like, men there must be a ton of things to learn. I followed and have updated my router class. Thanks Gio. Awesome. I'm moving on...

[@ProgramWithGio]

Its not about learning ton of new things, its that this codebase is for education only, it lacks some important features that you would get from a full scale framework like Laravel or Symfony.

[@Zubbee]

[@iambasanta]

This whole tutorial playlist is outstanding. Learning a lot of things from you. Thank you !!! Would you make a video on when to use a framework , If the problems can be solved with vanilla PHP then is it worth to do it with framework? I know framework increases the development speed. But using it for smaller projects ? What are your opinions I would love to hear it.

[@ProgramWithGio]

Thank you 💙. Yes I'll make a video about that, can't give an exact time but towards the end of the series probably. My opinion is that unless the app is very small, using a framework will only speed up the work. I personally use Laravel for pretty much everything.

[@lahoucineoldakdim7778]

For simplesity and perfermance, In this case of routing I prefer to include a config file return array of all routes and merge it with array variable in the Route::class

[@ProgramWithGio]

For sure, its fine if you have a few routes but as you add more routes then extracting it to a config routes file is the better way. Great tip 👍

[@lahoucineoldakdim7778]

@@ProgramWithGio Yes, suppose we have a folder named routes contains: web.php , api.php and admin.php We can load it easy using this loop: foreach (glob(__DIR__ .'/routes/*.php') as $route) { require_once $route; }

[@MrLion22]

Hello, you make really great videos and I look at them with great enthusiasm. But one thing I miss here, namely: independent of a 3rd framework (such as Slim), how could you form a group here with the router class? I lack this here and also the know-how for it. I would be very happy if you could also make a separate video for this. Thank you in advance.

your job is very great. appreciated you. but a lot of things we not understand. if I compare with other programmers, you are tackle a problem with complex method. I don't know if I have the basic skills of php or your method is complex? please explain. but don't mind bro

[@ProgramWithGio]

I'm not sure what you mean. What problem did I tackle with complex method? Attributes is not complex, it's a feature that I'm explaining and providing a usecase. If it seems complex then you can start from first section maybe, are you following the series from the beginning? Note that this is third section of the series which is advanced PHP, so if it seems hard I would advise to watch the series from the beginning. There are a lot of videos in first & second sections

[@cirhanne]

RegisterRoutesFromControllerAttributes has a nested loop it can be very slow if you have many routes + many http requests. This method is called in every http request right?

[@ProgramWithGio]

Yes, there needs to be a caching layer for a more optimal solution. This is just an example demonstrating how attributes can be used for routing.

Not directly since it's not a PHP thing. Might use it in a project though

[@codewithsheikh2805]

Do i need to understand reflection Api before I can use Attributes

@@ProgramWithGio ok so I'm beginner in php do i need to know about this before i can start learning some framework?

[@ProgramWithGio]

@@codewithsheikh2805 there are other topics you should be familiar with before moving into frameworks. Attributes isn't really necessary for that. Best way to know is to start the framework and if you get stuck or don't understand something, then learn about that specific topic and do it in parallel.

[@codewithsheikh2805]

@@ProgramWithGio thanks bro.

[@truthteachers]

Bro, i have one problem. At timestamp 12:23, I set the attribute "#[Route('/examples/generator')]". This works fine when the url has "/examples/generator" but fails when the url has the ending "/" like "/examples/generator/". I tried defining 2 attributes with the second one having the ending "/" and yet it failed stating i cannot have duplicate attributes. How do i address this problem?

[@ProgramWithGio]

You could modify the Router class (resolve method) and trim of any trailing slashes

[@truthteachers]

@@ProgramWithGio Bro, the problem resolved itself when we defined the attribute as repeatable. Then i defined 2 routes. It worked. But the trimming the trailing slashes would be a better option. Tq so much.

[@bakosyy]

Hey Gio. I see that you declare strict types by doing something on "

[@ProgramWithGio]

What do you mean? If you mean the autocomplete part thats just the IDE. Also I have it set up so that it adds strict types to all new PHP classes created within the IDE

[@bakosyy]

@@ProgramWithGio yup, I mean IDE set up that adds strict types to all new PHP classes. What do you use for that?

​@@bakosyyit's just a setting on PHPStorm. I believe it's a PHP stub template file. You can Google it and find how to edit it on PHPStorm

[@KIKOmanasijev]

Can we generate getters & setters functions for properties using Attributes? Ex: #[Getter] #[Setter] private $somePropertyName; This should generate the following functionality: getSomePropertyName(){...} setSomePropertyName(){...}

[@ProgramWithGio]

Not sure to be honest. You can use IDEs for that to generate getter & setters. If you mean dynamically then you can use magic __get & __set methods. Not sure I understand the use case.

What if controller class have more than one method , how $method will get the right method of controller class , video reference 10:44

Because route is defined in attribute & the method name is there on the controller method definition, keep watching & at around 12:00 you will see multiple methods within controller

I wish you could have done a separate video without all the Route stuff. This is for people whom find this and just want to use Attributes. Found one kzbin.info/www/bejne/pYTSZauYhZuNj9E&ab_channel=GaryClarke

[@ProgramWithGio]

Well, in this playlist the Route part fits in nicely. You can use Attributes for many different scenarios, Routing is one of them & a good example as well

[@Wane-maxx]

How would you handle query and url parameters?, this is too much code for a simple custom router, which makes it stressful and by far, a tool for a production.This is why PHP is a nightmare and unreliable for building serious web applications.

[@ProgramWithGio]

Query Params can be gotten with GET sulerglobal so not sure what's the issue with that. Url param handling can be built multiple ways, regex, reflection API, etc. This of course is not for production use, it's just an example demonstration of how frameworks implement things. For production, there are plenty of routing libraries that exist & frameworks that provide such features, Symfony/Laravel included.

[@bernhardd626]

This is a anti-pattern way of programming. Use interfaces for routable controllers instead and register it by calling the interface method. Much clearer. Using the reflection class is never a good way of programming.

[@ProgramWithGio]

I respectfully disagree. Don't see this as antipattern, most popular frameworks use both attributes/annotations & reflection API so not sure what you mean?

[@bernhardd626]

@@ProgramWithGio My main point is that there are other and clearer options. I observe that in practice the Reflection API is used too often and incorrectly, resulting in cluttered and poorly maintainable code. Please always try to find another solution first, typically with interfaces.

[@ProgramWithGio]

@@bernhardd626 we didn't use it wrongly or poorly in this video. Reflection API exists for a reason and Attributes is a great feature which you can't really use without Reflection API. Doing routing via attributes/annotations is a very common practice & there is absolutely nothing wrong with it. As I said before most popular frameworks utilize Reflection API the same way and use it pretty often in their source.
