How to create a property inside a method?

Question

PHP

Tired of working with an array. I want to change the method

public function setData(array $data):void{
  $this->data = $data;
}

on the

public function setData(array $data):void{
  foreach($data as $k => $v){
    $this->$k = $v;
  }
}

1. Do they do it?
2. How to do it?) I tried using __set, I didn’t understand something. This is the first time I have encountered such a need.

1. Do they do it?

They do, but it's not good practice. Firstly, you have a chance to erase some of the object's configuration data and get unpredictable behavior. Secondly, if you have values ​​from a database or other storage in the key-value format, it is better to store them in a separate field, the same date, but in the form of stdClass, so as not to confuse them with other fields when working with storage, like this:

public function setData(array $data):void{
  $this->data = (object)$data;
}

Ideally, you should have a DTO (data transfer object), but it is usually not used in asset record engines.
