hey chris... thanks!!
but what do you mean by "...escape output!!" is that output of the query, which is input to the db? as i understand it, you escape the query vars, after filtering/validation, that you're going to touch the db with... (insert/update/select) am i on your same wavelength?? -bruce -----Original Message----- From: Chris Shiflett [mailto:[EMAIL PROTECTED] Sent: Thursday, September 22, 2005 7:15 PM To: [EMAIL PROTECTED] Cc: 'Chris W.

You're reading the wrong articles. :-) Escaping is something you do to preserve data, period. If you have data that is going to enter a context where it can be considered anything other than data, it needs to be escaped. I often simplify this by suggesting that you always escape output. I did a podcast about this topic a few weeks ago: http://pro-php.com/index.php?post_id=10 I also wrote a small followup blog entry: http://shiflett.org/archive/133 Hope that helps.
