each word new link

in the database field:
s:11:"word1,word2";

<?
			$row['keywords'] = unserialize($row['keywords']);
			$row['keywords'] = str_replace(',',' ',$row['keywords']);
			?>
			<?=$row['keywords'];?>

PHP:

prints:

word1 word2

Code (markup):

i want to echo each word into a link:

echo '<a href="http://www.domain.com/search.php?q='.$row[keywords].'"</a>';

PHP:

so it's like:
word1 word2
