PHP 関数でエラー処理とログ記録を行うにはどうすればよいですか?

function divide($num1, $num2) {
  try {
    $result = $num1 / $num2;
  } catch (DivisionByZeroError $e) {
    // 如果除以零，则处理错误
    throw new Exception("Division by zero");
  }
  return $result;
}

function logError($message, $file, $line) {
  error_log("[$file, line $line]: $message", 3, "error.log");
}

function calculateAverage(...$numbers) {
  try {
    if (count($numbers) === 0) {
      throw new Exception('No numbers provided');
    }
    $sum = 0;
    foreach ($numbers as $num) {
      if (!is_numeric($num)) {
        throw new TypeError('Not all elements are numeric');
      }
      $sum += $num;
    }
    return $sum / count($numbers);
  } catch (Exception $e) {
    logError($e->getMessage(), __FILE__, __LINE__);
    throw $e;
  }
}
