I've created a patch with an addtional bool to strip_tags() with which you can use the $allowable_tags parameter as a blacklist instead of a whitelist. Examples: strip_tags('<a>Click</a><b>here<b>', '<a>'); => <a>Click</a>here strip_tags('<a>Click</a><b>here<b>', '<a>', false); => Click<b>here</b> ------------------------------------------------------------------------ [2003-05-20 13:47:14] eric at evilwalrus dot com Right now strip_tags() is a great function. You specify a string and the tags you want to keep. What I would like to see is another argument in strip tags so that you could tell it to keep or remove the tags you specify. I saw bug #5976 that had something to do with this very thought, but this extends the idea further. For example, if I have a string full of HTML and I want to remove all <script> and <meta> tags but keep the rest, I could do something like strip_tags($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. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=23723&edit=1
