Bug #62314 [NEW]: strip_tags - Only one iteration

From: FireFart at gmail dot com Operating system: PHP version: Irrelevant Package: *General Issues Bug Type: Bug Bug description:strip_tags - Only one iteration Description: ------------ The "strip_tags" function strips tags only in one iteration. So the following string can be used to bypass the strip_tags functionality. I'm not sure if it's a bug or a documentation issue, because a warning on the docs would also do the job.
