Syntax

phpnew ErrorException(
  string $message = "",
  int $code = 0,

    echo ' Severity: ' . $e->getSeverity();
  }
?>

  }
  
  set_error_handler('errorHandler');
  
  try {
    strpos(); // Idadi isiyo sahihi ya hoja
  } catch (ErrorException $e) {
    echo 'Caught exception: ' . $e->getMessage();
    echo ' in ' . $e->getFile();
    echo ' on line ' . $e->getLine();
  }
?>

    throw new ErrorException('Warning message', 0, E_WARNING);
  } catch (ErrorException $e) {
    echo 'Severity level: ' . $e->getSeverity();
    echo ' Is warning: ' . ($e->getSeverity() === E_WARNING ? 'yes' : 'no');
