PHP Form Validation - with PHP4+ and register_global = off
- The validation of data that has been entered in a form is necessary in most cases. Why is important? For example, what good is holding a contest or sweepstakes if you can''t notify the winner, because he or she entered an invalid telephone number or an incorrect address. What good is having a mailing list if the e-mail addresses on it aren''t verified, and your mailing list just bounces back to you without reaching the subscribers and target audience.&<br /&>&<br /&> Validating form entries saves you time and more importantly, it can save you money. And since somebody embossed the slogan &"Time is money!&", this should be very important for your web site!&<br /&>&<br /&> Well when should we validate? There are two types of validation; client side and server side.
