i want to implement an authentication scheme where the user enters his/her email in a form and once they hit submit, they are sent an email with a link. &nbsp;once they click the link, a cookie is put on their machine. &nbsp;the only catch is that i want the link to expire: they would have to click it within 2 hours from the time the email was sent. &nbsp;

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
