#5: Dependency inversion principle (DIP) in PHP, Laravel | SOLID Design Principles

[@QiroLab]

This is similar to the Dependency Injection concept.
- Dependency Injection is an implementation technique for populating instance variables of a class. Typically passing dependencies via one of the following: A constructor, A public property or field, A public setter
- Dependency Inversion is a general design guideline that recommends that classes should only have direct relationships with high-level abstractions.

Hello,You have public function __construct(StripePaymentMethod $stripePaymentMethod) {$this->paymentMethod = $stripePaymentMethod} above this you have public $paymentMethod; Now we can use $this->paymentMethod in other functions. But In PHP 8, We can use it straight, $this->stripePaymentMethod without using the `$this->paymentMethod = $stripePaymentMethod` inside constructor and not needed `public $paymentMethod; ` too.

Thanks a lot 😍
Now, we could say that SOLID principles are one unit depend on each other, I mean when we need to using SOLID should using all of them in the right way.
It is not right to use one or two of them and overlook the other principles.

I love Laravel and spring boot because of IoC, have developed Android applications in the past but I got confused with dependency injection setup. In Laravel it is a cinch perhaps you could jog our minds on that Mr tutor, unfortunately have never heard say your name.
