Redirect to another page

Redirection in PHP is a simple operation that allows you to send the user to a new page after a particular action or event (such as a successfully submitted form or a login to an account).

The key function for accomplishing this is the use of the HTTP header via PHP's header() function.

Using header

The header() function sends a raw HTTP header to the browser before any content is rendered on the page.

To redirect a user, the header you need to send is a Location instruction.
