I use PHP validation for my sites it is better then java script validation ?
How are you? I would like to thanks for give your comment.
no problem, hope you'll find it useful for you.
Welcome to SitePoint by the way
Neither is better since they serve two entirely different purposes.
PHP validation is your validation. It ensures that the information you receive is what you expect to receive and rejects anything that isn't correct. Without it there is nothing to stop you from receiving JUNK.
Two barriers are better than one.
