PHP Anonymous Classes - Full PHP 8 Tutorial

Показать описание

In this lesson, you will learn what anonymous classes are in PHP, how to create & use them. Anonymous classes like anonymous functions are nameless. You are able to create one-off objects using anonymous classes. You can either assign an anonymous class to a variable that will simply give you the object of that anonymous class, or just pass it as an argument since it's just an expression.

Note that at 4:54 I copied constructor promoted properties & pasted them into the anonymous class. Promoted properties should not be used inside an anonymous class when you are extending from a base class since those already exist on the base class.

I came to this video because I have a need for local classes but I don't need the full 'class file' etc.
This was exactly as I needed! It is explained really well and shows the advantages and limitations clearly. An excellent 8 minutes spent!
Thank you. Appreciated. :)

p.s. My 'use case' is that I have an array and I need to add a couple of functions to easily use the values of the array in testing. Anonymous classes are the perfect answer for this. :)

I was about to ask for the use cases, as they were discussed at the end. Very nice

I struggled with wrapping my head around Anonymous Functions so you can imagine how I felt when I reached this topic. But it was easier to understand this time. Plus the use case you talked about helped to put things in place in my mind. Thanks Gio.

Anonymous classes are essential for tests. Thanks a million!

Great video did not know about anonymous classes

Kind of mind blown by the use of anonymous classes in testing.

Can you explain why did you use promoted properties in both constructors? I think it should be used only in parent constructor for clarity that you are not creating the same properties in Child Class.

Thank you very much, great video as usual

Gio, how do you insert "public" to 3 parameters in __construct simultaneously? What PHPStorm shortcut it is?
