How to explode a string and create hyperlink?

You can use PHP function preg_replace() or str_replace() then used here-docs for creating hyperlink.
Instead of Echo Hear Docs is much better solution.
And at last removed the last Comma, and return your comma separated Dynamic links.

$tags = "jQuery Tutorials, PHP Display Errors, Drupal Module";
$tagL="";
function b2b_article_LinkedTags($stringTags) {
	$expTags = explode(",",$stringTags);
	foreach($expTags as $key=>$Tagevalue) {
	$Tagevalue = trim($Tagevalue);
	$link = preg_replace('/[^-a-z0-9]/', '-', strtolower($Tagevalue) );
	//$link = str_replace(" ","-", strtolower($Tagevalue));
	$tagL.=<<<EOF
	   <a href="./articles-tagged-$link">$Tagevalue</a>,
EOF;
	}
 
	return substr($tagL, 0, -1);
}  
echo b2b_article_LinkedTags($tags)
