为什么我的对象在构造和返回之后是空的？

Question

I tried creating an object in PHP for PHPMailer to be used in development enviroments.

class Configuration
    function __construct()
    {
    // creating an object for configuration, setting the configuration options and then returning it.
         return $config = (object) array(
             'DevEnv' => true,                      // DevEnv setting is used to define if PHPMailer should use a dev mail address to send to or not.
             'ReceiverEmail' => '[e-mail]',  // Set the develop enviroment email. 
             'ReceiverName' => 'name'              // Set the develop enviroment email name.
         );
    }
}

Then I call the class in another controller:

protected $configuration;
function __construct()
{
    $this->configuration = new Configuration();
}
function SendInfoMail()
{
            foreach($this->configuration as $config) {
                var_dump($config);
                if ($config->DevEnv == true) {
                    // do stuff
                }else{
                    // do stuff
            }
        }

for some reason, it just dumps an empty object. I also tried using

  var_dump($config->ReceiverEmail);

Constructors do not work that way. They do not have a return value – http://php.net/manual/en/language.oop5.decon.php

new ClassA always returns an instance of that class.
