Link to the same page but without ?arg=value parameters

Question

How to create link in Drupal 7 that will redirect me to the same page but with omitting "?arg=value" query fragment?

The following code doesn't work, as it always add ?arg=value.

<p><?php echo l(t('My Label'), 'views-page-url'); ?></p>

<p><a href="<?php echo $_GET['q']; ?>"><?php echo t('My Label'); ?></a></p>
