/*--------------------------------------------
| Usage example - you have to be in the loop |
---------------------------------------------*/
// Ex 1: print your tags
$tags = get_the_tags();
strip_html_from_tags($tags); // this will echo out the tags
echo "";
// Ex 2 (using the 2nd parameter)
$tags = get_the_tags();
$tags = strip_html_from_tags($tags, false); // you may save them for later usage
// An example of the above usage (passing the 2nd parameter) would be:
$myStrippedTags = explode(', ', $tags);
// now $myStrippedTag is an array of tags - do something to each of them
foreach($myStrippedTags as $tag)
{
// Maybe you would like to link them back?
// ...but I found this unnecesary to link them back - because you will reinvent the "the_tags" function
echo "<a href='".get_bloginfo('url')."/tag/{$tag}' title='{$tag}'>{$tag}</a>";

Well – I did the best I can to help you, as my english isn’t the best.
Hope you will find this useful.
