5: PHP Filter User Input - PHP MySQL Course

In this PHP tutorial I will demonstrate how to filter variables and user input (GET & POST) using the filter_var functions in PHP.
The filter functions of PHP are useful when sanitising mysql input that has been sent via the user.
These functions can also be used for form validation and variable checks

We are going to use the same MYSQL queries that we used in the previous tutorials so if you haven't seen them already do check them out.
