Avoiding code repeating in RESTful APIS PHP

Question

Since my last question related to this I have managed to create a working base and to understand how MVC works.

I'm writing RESTful APIS in PHP, they serve the purpose but I see that my code is repeating.

For example, for each action, I have a controller, a service... etc and a lot of that code can be reused not that I write a ton of code for one simple route.

I have tried a few of my ideas but I end up having spaghetti code and it does not look clean.

Here is folder the structure in one of my APIS.

For each activity I have a controller, that controller has a service injected into it via DI over yml.

When the service loads I have a domain folder where I keep my logic and over a factory, I create mappers there which I need(if I need them).

Each domain does one action, for example version workout(I need this for auditing of my data in MySQL).

Than I have a middleware in my service which does cashing(I'm working to change)

And thats basically how each of my routes works a lot of repeated code.

It looks very boring to write code now and I need a push into another direction.

Here is a part of my code:

index.php

$kernel = new Kernel('dev');

Take the following Kernel class:

class Kernel
{
    protected $env;

    const ENV_TYPE_DEV = 'dev';
    const ENV_TYPE_PROD = 'prod';

    public function __construct($env = null)
    {
        $this->env = $env ?? self::ENV_TYPE_DEV;
    }

    /**
    * Loads the container configuration.
    */
    public function registerContainerConfiguration()
    {
        if ($this->env === self::ENV_TYPE_DEV) {
            $configuration = 'config-development.yml';
        } else {
            $configuration = 'config-production.yml';
        }

        return $configuration;
    }
}

The changes I made are as follows:

Defined two constants so you can reference them rather than passing a direct string as the $env. This also gives you the option to change the values in the future without having to consider hardcoded versions of the values
Simplified your if statement (via the null coalescing operator) in your __construct to set the $env property to whatever is passed to ENV_TYPE_DEV as a default
In registerContainerConfiguration I removed your casts as they were redundant and turned the hard-coded string into the respective const

Then your index.php file:

use Symfony\Component\HttpFoundation\Request;
// load vendor
require __DIR__.'/../vendor/autoload.php';

// autoloading done through composer
// error handling based on kernel env
// type that is passed.

// new kernel
$kernel = new Kernel(Kernel::ENV_TYPE_DEV);
$bootstrap = new Bootstrap;

// new request
$request = Request::createFromGlobals();
// loader interface
$config = $kernel->registerContainerConfiguration();
// response from
$response = $bootstrap->handle($request, $config, null);

The changes I made / suggest are as follows:

You should have your error reporting work in conjunction with your environment that is defined in your Kernel
You should autoload your classes through composer
I changed the hardcoded dev string to the defined constant

In your AddWorkoutDomain class, I'd simplify the handle function:

/**
  * Handle 
  * 
  * @param Workout $workout
  * @return array
  */
  public function handle(Workout $workout):array
  {
      // beggin transaction
      $this->repository->begginTransaction();

      $messages = array_merge($messages, $this->storeBase($workout), $this->storeNames($workout), $this->storeDescriptions($workout), $this->storeRounds($workout), $this->storeTags($workout));

      // commit transaction
      $this->repository->commitTransaction();

      return $messages;
  }

Merged the array_merge calls into one (pun intended...), as per the documentation, the second parameter can be a list of variables to merge, doesn't have to be one per function call

Miscellaneous

Opinionated but, you seem to have quite a few blank lines within your classes, I would reduce that down

In various places you check for null variables in long, drawn out, if statements:

if(!is_null($workout->getOffset()) && !is_null($workout->getLimit()) && !is_null($workout->getState())){
    return $this->workoutService->getWorkoutList($workout);
}

Consider the following:

if (isset($workout->getOffset(), $workout->getLimit(), $workout->getState())) {

}

I have implemented your changes, thank you! I won't accept your answer but I will upvote it. If you could go through the whole code and give me full feedback on my code and classes and how it can be reduced I will accept it then. — DaAmidza, Commented Apr 3, 2019 at 6:41

Since nobody answered my question probably because I have not explained what I want here is an answer which satisfied my needs.

I have been wondering in the dark than I have found this answer which expanded my knowledge regarding programming.

I have seen some of those methods but I have never taught of the level of abstraction which they can bring.

As the accepted answer states:

Programming: Writing a program that creates, transforms, filters, aggregates and otherwise manipulates data.

Metaprogramming: Writing a program that creates, transforms, filters, aggregates and otherwise manipulates programs.

Generic Programming: Writing a program that creates, transforms, filters, aggregates and otherwise manipulates data, but makes only the minimum assumptions about the structure of the data, thus maximizing reuse across a wide range of data types.

I saw that I have been typing code which can be easily avoided.

Long story short here is my implementation to the issue I had.

My controller is still not there where I want it to be but I have managed to call my actions like this:

   return $this->baseService->actionHandler($exercise,
        [
            BaseService::ACT_GET_NAME,
            BaseService::ACT_GET_DESC,
            BaseService::ACT_GET_BASE,
            BaseService::ACT_GET_OBJ
        ],
        $queryParams
    );

And my service looks something like this:

class BaseService
{

    // vars
    private $domainRepository;
    private $responseBootstrap;
    private $versionDomain;
    private $nameDomain;
    private $tagDomain;

    const ACT_VERSION = 'versionUp';
    const ACT_CREATE = 'createObject';
    const ACT_SINGLE_OBJ = 'returnSingleObject';
    const ACT_CRE_NAME = 'createName';
    const ACT_CRE_DESC = 'createDescription';
    const ACT_CRE_TAG = 'createTags';
    const ACT_CRE_BODY = 'createBody';
    const ACT_CRE_PKG_PLAN = 'createPackagePlan';
    const ACT_CRE_WRK_PLN_DAY = 'createWorkoutPlanDay';
    const ACT_CRE_ROUND = 'createRound';
    const ACT_RELEASE = 'releaseContent';
    const ACT_DELETE = 'delete';

    // actions delete 
    const ACT_ED_NAME = 'editName';
    const ACT_ED_OBJ = 'editObject';
    const ACT_ED_DESC = 'editDescription';
    const ACT_ED_TAG = 'editTag';
    const ACT_ED_ROUND = 'editRound';
    const ACT_ED_BODY = 'editBody';
    const ACT_ED_DAY = 'editDay';
    const ACT_ED_PKG_PLAN = 'editPackagePlan';

    // actions get
    const ACT_GET_NAME = 'getName';
    const ACT_GET_DESC = 'getDescription';
    const ACT_GET_BODY = 'getBody';
    const ACT_GET_OBJ = 'getObjectResponse';
    const ACT_GET_BASE = 'getBase';

    // system actions

    }

    ...........

The BaseService class has all the actions and it calls the DAO layer which is flexible enough to construct the query I need.

I need to add a caching layer to it and a few more things but this is the answer which I have been asking for(at least I think so if somebody else had a better version of it feel free to post your answer.
