How to make a Callback in the class method of your module for 1C-Bitrix?

Question

PHP

Good afternoon,
for the module used by users from the marketplace (1C-Bitrix), it is necessary to add the ability to change, if necessary, the results of the class methods.
To implement the callback, I used the call_user_func function. Perhaps 1C-Bitrix already has its own Events that can be registered and assigned to your module?
At the moment the code has the following structure:

class myClass {
  public function import()
  {
    $arResult = array();

    $arData = array(
      'result1',
      'result2',
      'result3',
    );

    foreach($arData AS $v)
    {
      $arResult[] = 'Строка: '.$v;
    }

    if(function_exists('call_import'))
      $arResult = call_user_func('call_import', $arResult);
    
    return $arResult;
  }
}

function call_import($arData = array())
{
  $arResult = array();
  foreach($arData AS $v)
  {
    $arResult[] = $v.' что то изменили';
  }
  return $arResult;
}

this method will allow the user to create his own call_import function and change the result of the import method.
To what extent is this decision correct?
Thank you.

Answer 1

Of course, you need to use standard events .

Answer 2

class myClass {
  public function import($callback = null)
  {
    $arResult = array();

    $arData = array(
      'result1',
      'result2',
      'result3',
    );

    foreach($arData AS $v)
    {
      $arResult[] = 'Строка: '.$v;
    }

    if (is_callable($callback)) {
        call_user_func($callback, $arResult);
    }
    
    return $arResult;
  }
}
