How to get the canonical SEF URL of an article in PHP?

Question

Is there any way to get from the article it's SEF URL?

<?php
   $id = JFactory::getApplication()->input->getInt('id');
   $article = JTable::getInstance("content");
?>

searching something like this:

<?php echo $article->somethingLikeCanonicalSEFURL; ?>

To get SEF URL, pass non-SEF URL through JRoute::_(). To get non-SEF URL, you can use ContentHelperRoute::getArticleRoute().

// Load route helper class.
JLoader::register('ContentHelperRoute', JPATH_SITE . '/components/com_content/helpers/route.php');

// Build non-SEF URL.
$nonSefLink = ContentHelperRoute::getArticleRoute($article->id . ':' . $article->alias, $article->catid, $article->language);

// Build SEF URL.
$sefLink = JRoute::_($nonSefLink);
