What is the best way to remove the characters from strings that may cause security problems? Namely, `, ', ", <, >, \ and all non-printing strings. Did I miss any? Thanks.Why do you need to remove them? So I can't type <grin>? Is that a security violation? All you need to do is use htmlentities() and/or addslashes() to protect data being displayed or entered into a database. -- ---John Holmes...
