verify a user via e-mail in PHP

Question

I\'m actually creating a web application using PHP and seek help verifying a user. As with certain websites, when you register, an e-mail is sent to you with a confirmation

Answer 1

This is a very broad question, so we can only give a broad answer, but the general technique to do so is

1. insert the user's email address into your database but mark it as unverified
2. create a unique registration key and insert it into a different table just for these keys
3. send an email to the user's email address with a link to your site that passes this registration key as an argument (eg http://site.com/confirm.php?key=1234)
4. when that url is visited, mark the email as verified and remove the temporarily created registration key
