Re: [PHP] "nullifying" php and html tags?
Yes, there is a function strip_tags(). Also look at the functions, htmlentities() and htmlspecialchars().

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.

[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. is there anyway to "disable" any html or php tags that the user might have typed in? it seems pretty dangerous to allow a user to enter any amount of php programming at their will. something as simple as a function that strips all <'s and >'s would work just as well i would imagine. thanks! -mark __ Do You Yahoo!?
