PHP Form Handling

This lesson is part of PHP · All levels

Summary

Forms are the primary way the web receives data from users, such as logins, comments, or registrations. This lesson explains how PHP reads form data through the superglobal $_GET and $_POST according to the method attribute on the form tag. You also learn how to safely display the input results back to the page.

Key points

The method attribute on the form specifies input data via $_GET or $_POST
The action attribute value determines the URL of the form processor
Use $_POST for sensitive data because it doesn't appear in the URL
Always escape output form with htmlspecialchars() when displaying back
