How to do not repeat similar function over and over-CodePudding

I have over 20 similar function and looking for way to not repeat same thing every time when i create new function

Is there anyway to make it dynamic/smart ?

Index function is receive calls from other server, they can pass function name and data to index

public function index() {
 if (isset($this->request->post)) {
  $data = $this->request->post;
 if ($this->api_key($data['key'])) {
  call_user_func(array($this, $data['function_name']),  $data);
  }
 }
}

This are the similar functions

        public function addDelivery($data) {
      if (!empty($data)) {
        $this->load->model('api');
        $query = $this->model_api->addDelivery($data);
        if ($query === true) {
          $json['success'] = true;
        }else{
          $json['error'] = $query;
        }
        echo json_encode($json);
      }
    }

    public function addStatus($data) {
      if (!empty($data)) {
        $this->load->model('api');
        $query = $this->model_api->addStatus($data);
        if ($query === true) {
          $json['success'] = true;
        }else{
          $json['error'] = $query;
        }
        echo json_encode($json);
      }
    }

    public function editDelivery($data) {
      if (!empty($data)) {
        $this->load->model('api');
        $query = $this->model_api->editDelivery($data);
        if ($query === true) {
          $json['success'] = true;
        }else{
          $json['error'] = $query;
        }
        echo json_encode($json);
      }
    }

    public function editStatus($data) {
      if (!empty($data)) {
        $this->load->model('api');
        $query = $this->model_api->editStatus($data);
        if ($query === true) {
          $json['success'] = true;
        }else{
          $json['error'] = $query;
        }
        echo json_encode($json);
      }
    }

CodePudding user response：

You could use call_user_func() to replace the extra functions, as long as:

You don't want to use those methods outside the index() method.
The name in $data['function_name'] matches the method you want to call.

It could work something like this:

public function index() {
    if (isset($this->request->post)) {
        $data = $this->request->post;
        if ($this->api_key($data['key']) && !empty($data)) {
            $this->load->model('api');
            $query = call_user_func([$this->model_api, $data['function_name']], $data);
            if ($query === true) {
                $json['success'] = true;
            } else {
                $json['error'] = $query;
            } 
            echo json_encode($json);
        }
    }
}

I cannot test this code, so I cannot be certain it works.
