This is what it needs to do!
The first tag that is found will set where the parser will insert '<!-- /
sc' before that tag. Any bbcode tags that are in the current tag will be
skipped over until the parser finds the end of the current bbcode tag it is
working on. Once it finds the end of the current tag it will insert 'sc
/ -->' after the end of the current tag. It will continue doing this until
no tags are left to be parsed in the string!
My script is below....
My question...
Is there a better way to do this?
// script!
<?
$res = array ( '<!-- / sc', 'sc / -->', '', '' );
$str = "[quote=tinyman,Jul 29 2005, 11:27 PM]
