Working with $_GET and $_POST in PHP

Heads up! This course may be archived and/or unavailable.

This course is a part of Intermediate PHP, a 8-course Track series from Treehouse.

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.

• Build a simple HTML form
• Use PHP Superglobals when accessing external data
• echo variables using query strings with $_GET
• echo variables using without query strings with$_POST
• Filter inputs with filter_input() for various input types
• Escape outputs with htmlentities(), htmlspecialchars(), and strip_tags()
• Develop a security-conscious mindset for all of your projects
