Safe Email Testing Solution

As developers or project staff it’s really hard to come up with a clean and safe email testing solution. You never want to send production emails but, really how do you test them.

I’ve recently found this service https://mailtrap.io/. You just add the email settings in your application however you usually would and all emails generated by your system will just display in your dashboard inside mail trap. Please feel free to check out this amazing service https://mailtrap.io/billing/plans

Implement dependency injection

Quick notes on implementing dependency injection

 

Most if not all PHP frameworks utilize dependency injection. Its allowing PHP to automate supplying function parameters. In my code example below in the class Test the function test requires the User class to be passed in as a parameter. Maybe you’ll want more things like Route or maybe some kind of Registry object. Having decency injection helps reduce redundant code by instantiating the function everywhere needed.

class user {
   public $id = 1;
}

class Test {
   public static function test( User $user ) {
      return $user->id;
   }
}

Here is a VERY basic example of how to implement PHP reflection.

$controller = Test;
$method = test;
$rm = new \ReflectionMethod($controller, $method);
$parameters = [];
foreach ($rm->getParameters() as $inc => $parameter) {
// Quick example getting the parameters and
// which class that parameter location is looking for
$class_name = $parameter->getType()->getName();
// Instatiate the new class
$parameters[] = new $class_name;
}
//Call the controller and method with the parameters you were expecting
call_user_func_array([$controller, $method], $parameters);

The idea is that PHP will use reflection to look at the method you are trying to call and figure out what parameters are expected. My example is simple, you can do a lot more. The idea is to present in note style form a starting point and to present the idea in a functional way.
