I want to preface this question with the fact that I am a student and this is my first PHP class. So, the following question might be a bit novice...
Okay so the point of this program was for me to filter results from a form through regular expressions along with clean up the text area content...
Well as of right now, all works fine except for the strip_tags bit. I have it set to allow the tags <b> and <p>, and when I enter regular text into the text area, it returns perfectly. If I enter something such as <b>lucky</b> you, all that is returned is 'b'.
I'll post my code. If anyone can give me a hand, I'd love it. At this point I'm overly frustrated. I've studied the examples my instructor supplied (mine is almost identical) and I've looked throught the PHP.net manual and from what I read it should work...
The working code is at http://www.lampbusters.com/~beckalyce/prog3b.php
