PHP - Rewrite dependencies classes

description.md

Class Alias

<?php

namespace Shop\Models;

use Shop\Models\Address as AddressClass;

/** @var Address parent */
class_alias(defined('AddressClass') ? AddressClass : Address::class, 'ThingPink\Shop\Models\AddressClass');

/**
 * Class BillingAddress
 *
 * @package Shop\Models
 */
class BillingAddress extends AddressClass
{
    ...
}

Pros

• Can simply extend the class that we need to overwrite some function and point the alias to it (do not need rewrite the entire class)

Cons

• Every file with this strategy lose IDE type hints from parent and eventually every type hints for classes with this strategy
• Need to add this alias code to EVERY class in order to make em "replaceable"

Class overwrite

composer.json

...
  "autoload": {
    "psr-4": {
      "Shop\\Models\\": "./extended"
    }
  },
 ...

Where inside the ./extended folder exists the class(es) that you want to reimplement.

Pros

• Do not need to change a thing in vendor classes in order to adapt extensibility
• IDE automatically just read the "overwritten" version, meaning that we get out of the box all the IDE hints

Cons

• Need to rewrite entire classes (instead just extend em and overwrite the desired changes)
