Dynamic setting of object properties, will it eat up a lot of performance?

Question

PHP

Essence in the following:
There is one method and one function. The method takes an array, escapes it, and returns. And the function takes an array and an object, after which it sets the properties of the received object to values ​​from the passed array.
So, I pass the super global $_POST to the method, after which I pass a clean array to the function and get the object I need with the given properties. But I wonder if these not cunning manipulations will have an impact on performance, and if so, how much.
Method:

public static function arrayEscape(array $array, $deliteEmptyKeys=false){
    if($deliteEmptyKeys){
    		foreach($array as $key => $value){
       		if(!empty($value)){
         			$clean[$key] = static::$db->escape($value);
       		}
    		}
    }
    else{
      foreach($array as $key => $value){
       		$clean[$key] = static::$db->escape($value); /* Вызывается метод экранирования строк, хранящийся в статической переменной $db */
      }
    }
    return $clean;
  }

Function:

function arrayToObject($object, array $arr){
  $prop=get_object_vars($object);
  foreach($arr as $key=>$value){
    if(array_key_exists($key,$prop)){
      $object->$key = $arr[$key];
    }
  }
}

I use it this way:

$clean = Db_querys::arrayEscape($_POST,true);
arrayToObject($object,$clean);

Instead of writing like this:

$object->prop1 = $db->escape($_POST['prop1']);
$object->prop2 = $db->escape($_POST['prop2']);

And so arbitrarily

Answer 1

There will be no performance impact if you have less than 100 POST requests per second.
