Services Container

The Apex\Svc\ namespace contains various PSR compliant and other items that can be easily pulled in via attribute / constructor injection to aide in your development. You may view the ~/boot/container.php file to see and change the specific implementations being used for each PSR compliant service (eg. PSR-3 logger, PSR-6 cache, PSR-18 HTTP client, et al).

Loading Services

Services should always be loaded via attribute or constructor injection, for example:

<?php

namespace App\Demo;

use Apex\Svc\{Db, Cache, View};
use App\Demo\Models\Product;

/**
 * Demo class
 */
class MyDemoClass
{

    #[Inject(Db::class)]
    private Db $db;

    #[Inject(Cache::class)]
    private Cache $cache;

    #[Inject(View::class)]
    private View $view;

    /**
     * Do something
     */
    public function doSomething():void
    {

        $value = $this->db->getField("SELECT something from some_table WHERE id = 5");

        $this->view->assign('some_var', $value);
    }

}
