Hello im trying to get the hang of using bb codes onto my normal php site ( not forum or anything just a normal site )

I have seen a few posts like this one http://www.pixel2life.com/forums/index.php?/topic/10659-php-bbcode-parser/

which says i need a bb parser. I was just wondering can anyone show me how i would use one ?

I have a status box were users can update there status but i would like to allow bb codes but not java script.

So when im doing my inserting into the db i strip the status like so..

$status= mysql_real_escape_string($_POST['status']);
$status2= strip_tags($status);

And that stops the java script and tags from getting though but i need the bb code tags to come though but carry on blocking the java script code is there anyway to do this ?

Also then i just echo it out

echo $status2 ;

But just plain text shows so was just wondering if anyone knows how to let though bb code and stop java script and could some one show me how to use the bb parasher ? also need to know how to echo out the bb coding...
