      The Action pattern is a relatively new design pattern that's become popular in the PHP community, particularly with Laravel Developers.

      The pattern is a simplified version of the Command pattern, with no separate Handler class. The Action class is responsible for the handling and execution logic.

      In most cases, an Action class only has a single public method called `execute()` or `handle()`, or uses PHP's `__invoke()` magic method.

      This is a different approach from a Service class that has multiple methods to perform different tasks.

      Here's a simplified version of the code of an Action from my website:

      ```php
      <?php

      readonly final class AddRandomCtaToDailyEmail {

        public function __construct(private EntityTypeManagerInterface $entityTypeManager) {
        }

        public function __invoke(DailyEmail $email): void {
          // Checks a call to action isn't already added.
          // If not, a random one is selected and added.
        }

      }
      ```

      Note the `DailyEmail` class is [a bundle class][0] I've created that extends the regular `Node` class.

      Different to a service, the class name describes the action being performed - usually starting with a verb followed by a noun to describe the action being taken and the object it's being taken on.

      It's a simple pattern that doesn't require additional packages or libraries, and it's easy to implement in different frameworks and other languages.

      Whether you call this an Action, Command or something else, I like that it encourages writing more structured code that's easy to read and test.
