its backing on this so u get error page
// Change new lines to . nl2br function probably would work also. It's probably the same as this though. And gets rid of htmlchars. htmlentities screws up the & stuff.

$content=str_replace(array(' ','','','','','// Change new lines to . nl2br function probably would work also. It's probably the same as this though. And gets rid of

PHP Code:
function dehtml($content) { $content=preg_replace('/&(?!(amp|[#0-9]+|lt|gt|quot|copy|nbsp);)/ix','&',$content); $content=str_replace(array(' ','','','','',''),'',$content); return str_replace(array('<','>','\'','"'),array('<','>',''','"'),$content); }
the code is getting filtered by bvlist editor , here is the function.
by the way parse is working for now except for the emotes / smilies (i think the unicodes are getting filtered.)
