With every new video I progress in this series, I get excited and excited all over again, it's unbelievable how great and in-depth this series is! Thanks gio for the investment!!!

[@ProgramWithGio]

Very happy to hear that you are progressing and videos are helpful, thank you 🙌

[@isaacsouza17]

Laravel really hides does detail for us, but it is important to understand the fundamentals, thanks again for the free high quality content, keep it up

[@ProgramWithGio]

Agreed. Pretty much all frameworks hide & abstract away such things. You're very welcome Isaac & thank you 🙌

[@mwaas]

You explain the hidden and essential things in frameworks. I will always be grateful to you

[@mauriciocastro7572]

just as a reminder, for the router to work the server must be configured so that it redirects traffic to index.php, i was stuck in this for days without realising gio had already setup his server a few videos ago haha. this is seriously the best guide on php programming, much love

[@ProgramWithGio]

Yea we covered that earlier. Thank you 💙. Here is the repo to outline that includes all videos in order: github.com/ggelashvili/learnphptherightway-outline

[@deZOO77]

Thx man. I've been strugling with this for few hours, wondering what I did wrong, until I saw your comment:)

[@VuPhuongThanh-BDCCN]

I use xampp and Could you help me how to configured router, i am very appreciate ?

[@salvaddd]

Omg it happened the same to me! I was wondering for a couple of hours what was the problem. Maybe a little note should be added about this, as for example I started a second environment for this video without configuring the index redirect.

[@tommauro2023]

Me too! For the ones that might have the same problem all the necessary configurations is in the tutorial about docker.

[@benderbg]

This lesson even if its just basics really shows how much work it takes to router a few pages and how awesome frameworks have become in speeding up that process.

[@ProgramWithGio]

Yup, frameworks make our lives a lot easier for sure

[@2008rol]

Agree with Isaac Souza. When first time I met Laravel, I really liked to know how its router works. But I found it was quite hard to trace. After watching this video, Gio gave me a lot more understanding on how router works. Thanks a lot

[@thiagoantonioferreira9614]

Okey sorry, i think i figured out the meaning. Its just an array with the instructions to call a function inside of a class, which the first position is the address of the class, and the second position is the function to be called, right?

Hey boss, I can't type hint the $message property. The error shows that "Type of App\Exceptions\RouteNotFoundException::$message must not be defined (as in class Exception)".

Hey Gio, or anyone listening... Thanks Gio for this course, it is fantastic! I'm just having an issue where if I try to call a method from a class like [classes\Home::class, 'index']; it gets called as an array with "classes\Home" and "index" as a string. Does this technique for calling methods from methods from classes not work anymore?

[@ProgramWithGio]

Hey, I'm not sure I understand the question, how are you calling the method? Do you use call_user_func_array?

[@louisolitaire424]

Hey Gio, I can’t thank you enough for making such a valuable content available on YT. That series is just amazing and the way you teach is brilliant! I have a quick question on this one though and I figured maybe you or someone else could help. I don’t understand how you can pass an array as the first argument in the call_user_func_array function. Is the array somehow casted into a callable? And if so, does it mean that we can invoke arrays shaped like this [App\MyClass, ‘method’]() ? Thanks again 😉Gratitude from France!

[@ProgramWithGio]

Hey, thank you for the kind words. In PHP callable can be defined as an array as well with first element being the object or the class name and the second element being the method. You can check the docs for the callable type for more info: www.php.net/manual/en/language.types.callable.php

[@louisolitaire424]

Thanks a lot for the explanation.

[@devanii]

i don't understand this piece [$class,$method] = $action the left side is an array which you replace with actin but it is still available later?

[@ProgramWithGio]

It's called array destructuring. We covered it in first section: kzbin.info/www/bejne/e2WphpiNlpiKh80 at around 13 min or so

[@nemac23]

10:50 Probably a dumb question, but why do this check? Why not always pass array to controller - what's the use of keeping callable option?

[@ProgramWithGio]

Not a dumb question at all. Its for convenience, you may want to register route based on a closure instead of an array. If you only want to use arrays you are free to do that.

[@Armando-px8hi]

Thank God Laravel exists 😂 Thank you GIO, just one question how did you learn PHP man, sometimes I just think it was written by you))

[@ProgramWithGio]

Laravel is awesome, so is Symfony. I always keep on learning new things, I don't know/remember everything off the top of my head every time. Sometimes I forget the simple things. The key thing is, being able to figure it out when its needed.

[@emekatimothyiloba699]

Hey Gio. Please why is the error message displayed that way "Uncaught RouteException". Is there not a way to display the neat error message??

[@ProgramWithGio]

Because its an unhandled exception, you can create exception handler or use try/catch

[@Nukker13]

For some reason, I get stuck on 8:33 part of the video, when the router is optimized to work with arrays. Any idea what could be fixed? It just throws the same routes error that is created earlier in this lesson, no idea why the URIs are not cathed properly.

How do you navigate to the "invoice' page and still end up showing 'resolve' on index.php? Can't follow your routing example here. All other tutorials are great!

[@ProgramWithGio]

Because all requests go through the index.php, thats where router is instantiated & proper route resolved

[@DanielKhadivi]

@@ProgramWithGio If you type a url ending in "/invoice" wouldn't that navigate to the "index.php" page? Why would it go to the main page at 'index.php'?

[@ProgramWithGio]

​@@DanielKhadivi Request goes to the index.php & then index.php invokes the router which decides which page to render

[@DanielKhadivi]

@@ProgramWithGio Thank you for taking the time to respond. I have defined a "About.php" page in a "Pages" subfolder. The PHP server is configured using IIS / FastCGI, not Apache. When I type "localhost/phpTutorial/App/Pages/About.php", it goes directly to that page The full path on OS is: C:\inetpub\wwwroot\phpTutorial\App\Pages\About.php This seems to be the correct behavior of navigating to web page. The "app" root is at: "C:\inetpub\wwwroot\phpTutorial\App" . Again, I see no reason for the request to go to the "index.php" at the root of the app (where I have done similar registration to yours in your video), and then somehow redirect itself to the "About" page. There is no redirection logic. Sorry, I'm new to PHP and love your tutorials. What am I doing wrong?

[@ProgramWithGio]

What you are doing doesnt really follow with what we are doing in this lesson. In this lesson we set up routing in a way so that all traffic is routed through public/index.php, so that acts as our front controller. Then we have the router that maps the request URI to the controller & the action, so when /about is requested it executes AboutController::index method & so on

[@stephen.cabreros]

w0w this is so good, I didnt know this syntax [App\Classes\Invoice::class,'index']( ) would work to call its method if index method is static

[@ProgramWithGio]

It's just an array. I wouldn't recommend having static controller methods.

[@OmarFedior]

Using XAMPP and can't get Routing to work? Try to check it out this video: kzbin.info/www/bejne/r6W5gZyPfrGtbpI Where Program With Gio explains step-by-step how to rewrite server rules.

new creates a new object of that class, Home::class just references the fully qualified class name

I had big problems with this routing... First, I could not make it work at all in Laragon folder; Then, since I have a small website & domain - I tried it in subdomain, and with small adjustments (for PHP 7.3, without Composer, on a shared hosting) - I was able to make this router work in subdomain's root; but then, I was trying to make it work in a Directory, I could not make it work; or may be I failed to set .htaccess right... even though - ChatGPT could not find a problem, but it didn't work.

[@truthteachers]

One of the odd things i find is that the info produced by $_SERVER differs terribly when I use xampp to run the script and when i use the PHP inbuilt server "php -S localhost:3000". I am using Windows 10 and PHP 8.1.12. This conflict becomes critical when i try to get REQUEST_URI parameter. When i use Xampp i get "/MyCoursesLG/php/courses/piocourse/src/public/" but when i use inbuilt server i get "/". This creates unnecessary coding variations especially when i tried to create basic routing. Why does this happen and how to resolve this?

[@ProgramWithGio]

Found this now, for some reason KZbin did not notify me about this. I've answered this to your comment in another video (2.25).
