Working with $_GET and $_POST in PHP

About this Course

This course will show you how to work with PHP Superglobals such as $_GET and $_POST while using a security-conscious mindset. External inputs, like HTML forms, are considered a security vulnerability so you should always filter inputs and escape outputs. Using PHP Superglobals when using external inputs such as HTML forms, cookies, sessions, and web servers will give you a security-conscious mindset that you can apply to all of your projects.

What you'll learn

• Build a simple HTML form
