I know it's a (very) old bug, but on occasion I need a "blacklist"
intead of a "whitelist" strip_tags() function.
I've created a patch with an addtional bool to strip_tags() with which
you can use the $allowable_tags parameter as a blacklist instead of a
whitelist.
Examples:
strip_tags('<a>Click</a><b>here<b>', '<a>'); => <a>Click</a>here
strip_tags('<a>Click</a><b>here<b>', '<a>', false); => Click<b>here</b>

Right now strip_tags() is a great function. You specify a string and the
tags you want to keep. What I would like to see is another argument in
strip tags so that you could tell it to keep or remove the tags you
specify. I saw bug #5976 that had something to do with this very
thought, but this extends the idea further. For example, if I have a
string full of HTML and I want to remove all <script> and <meta> tags
but keep the rest, I could do something like
strip_tags($string, '<meta><script>', true);
That boolean value of true as the third argument would tell the
strip_tags() function to remove the tags specified. Without that, it
defaults to the way it is now and removes all but those tags. I think
this would be a very handy thing to have in PHP. Thanks.
