RE: [PHP] nullifying php and html tags?
Hello. I just finished creating a simple input form in which the contents of a textarea get written to a file which in turn gets read by a particular page. This is a Really Bad Idea(tm). it seems pretty dangerous to allow a user to enter any amount of php programming at their will. ... and that's why. something as simple as a function that strips all 's and 's would work just as well i would imagine. You could just read the file from another script with file() and output it rather than include()'ing it. That way the code is never executed.

Yes, there is a function strip_tags(). Also look at the functions, htmlentities() and htmlspecialchars().
