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
  • 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
