我尝试在我的Symfony Sonata软件包中提供服务,以便在创建订单后立即向特定人员发送电子邮件.发送电子邮件的人是用户选择批准订单的人.

我尝试按照Symfony网站上的服务容器文档,但对我来说感觉太不完整了.我想看一个完整的例子而不仅仅是几个片段.

到目前为止,这是我的电子邮件服务类;

<?php

namespace Qi\Bss\BaseBundle\Lib\PurchaseModule;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Authorization\AuthorizationChecker;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage;
use Doctrine\ORM\EntityManager;

/**
 * 
 */
class Notifier 
{
    /**
     * Service container
     * @var type 
     */
    private $serviceContainer;


    public function notifier($subject, $from, $to, $body) {
        $message = \Swift_Message::newInstance()
            ->setSubject($subject)
            ->setFrom($from)
            ->setTo($to)
            ->setBody($body)
        ;
        $this->serviceContainer->get('mailer')->send($message);
    }

    /**
     * Sets the sales order exporter object
     * @param type $serviceContainer
     */
    public function setServiceContainer($serviceContainer)
    {
        $this->serviceContainer = $serviceContainer;
    }
}

我的services.yml文件中的服务看起来像这样;

bss.pmod.order_notifier:
    class: Qi\Bss\BaseBundle\Lib\PurchaseModule\Notifier
    arguments: ["@mailer"] …

我有一个数组,像这样返回对象:

array (size=61)
  0 => 
    object(Xxx\Car)[602]
      private 'id' => int 53
      private 'name' => string 'Volkswagen' (length=10)
  1 => 
    object(Xxx\Car)[594]
      private 'id' => int 43
      private 'name' => string 'Toyota' (length=6)
  2 => 
    object(Xxx\Car)[595]
      private 'id' => int 32
      private 'name' => string 'BMW' (length=3)

如何将数组转换为id成为键和描述值,如下所示:

array (size=61)
  53 => 'Volkswagen'
  43 => 'Toyota'
  32 => 'BMW'

我试过了

$cars = array();    
foreach ($result as $key => $value) {
    $cars[$value['id']] = $value['name'];
}

但这不起作用.
