Usage

Use helper methods

    // register class
    di_register(Tools::class)
    
    // Call a method in a class
    di_register(Tools::class)->generate($param, $param, $param)
    
    // more
    di_register(Tools::class)->foo($bar)

example

Sometimes we need dependency injection when calling our own defined methods. See the example below.

<?php

namespace App\Services;


use App\Tools;
use App\User;
use Cache;
use Petstore30\Order;

class OrderService
{
    /**
     * place order
     *
     * @param User  $user
     * @param       $goods
     * @param       $address
     * @param Cache $cache
     * @param Tools $tools
     */
    public function placeOrder(User $user, $goods, $address, Cache $cache, Tools $tools)
    {
        // code something
    }

    /**
     * pay
     *
     * @param Order $order
     * @param Cache $cache
     * @param Tools $tools
     */
    public function pay(Order $order, Cache $cache, Tools $tools)
    {
        // code something
    }

}

Then we easily use the method of dependency injection

    /**
     * store
     */
    public function store()
    {
        di_register(OrderService::class)->placeOrder($user, $goods, $address);
    }

or

    /**
     * store
     */
    public function store()
    {
        $orderService = di_register(OrderService::class);
        
        $orderService->placeOrder($user, $goods, $address);
        $orderService->pay($order);
    }
