Validating forms using php

Bob receives the mail and clicks the URL, demonstrating to Alice that he controls the email address he claimed to have.If instead a hostile party, Chuck, were to visit Alice's website attempting to masquerade as Bob, he would be unable to complete the account registration process because the confirmation would be sent to Bob's email address, to which Chuck does not have access. The step of email address verification (confirmation) is considered by many anti-spam advocates to be the minimum degree necessary for any opt-in email advertising or other ongoing email communication.Using a confirmed opt-in (COI) (also known as a Double opt-in) procedure helps to ensure that a third party is not able to subscribe someone else accidentally, or out of malice, since if no action is taken on the part of the e-mail recipient, they will simply no longer receive any messages from the list operator.Mail system administrators and non-spam mailing list operators refer to this as confirmed subscription or closed-loop opt-in.Bob supplies an email address at which he can be contacted, but Alice does not yet know that Bob is being truthful (consciously or not) about the address.
