named arguments were added not because you can forget the order of the arguments...
the reason is to be able to provide only needed arguments and not specify arguments that have default value
for example:
public function foo(string $bar1 = 'bar1', string $bar2 = 'bar2', string $bar3 = 'bar3', string $bar4 = 'bar4')

in 7.4 if you wanted to change `$bar4` you needed to provide all the previous arguments, but in php 8.0 you can do just that
foo(bar4: 'bar5')

I just loved the nullsafe operator .. that's will help a lot

[marvindawson]

Thank you so much for demistification JIT compiler. You simply show 2 images and I finally feel that I understand the benefits of JIT.

Excellent recap of PHP8 . Well and simply explained.

[EduardoWeidmanBarijan]

Nice explanation. I like to see the old code being refactored to the new code. But I didn't understand the Attributes portion. All I could understand is that it is something that frameworks will use and not my own code. I would like a video explaining it in more details with production-like code and what is the advantage of using Attributes. Thank you very much.

PHP is like the first love, you hate it when you get over it

[AbhinavKulshreshtha]

Amazing Video . To the point explanation. While the reddit world is debating if php is alive or not, php 8 is turning up to be as good as kotlin or Java. And here in my stupid job, we still maintain websites in php 5.4.

I need to subscribe to your channel and see what you upload next.

[jessekoerhuis]

Awesome video! The features are made very clear by your examples!

[martirosyanara]

Thank you for the video, was nice to see Georgian scripts on the screen :)

[CrackerWeb]

Your composer.json already has psr-4 format to read the files in src, use namespace to read file, no need to use include or require.
Nice video by the way.

[music-unleashed]

Nice video again!
I never used ?? and = like you in the getReviews function (??=) at 39:42 ...
I learned something new again, but seeing this I can understand why so much devs just hate PHP :)
It wasn't obvious even for me at first.
