Securing $_POST cheat sheet (from http://stackoverflow.com/posts/3126175)

#Stop!

You're making a mistake here. Oh, no, you've picked the right PHP functions to make your data a bit safer. That's fine. Your mistake is in the order of operations, and how and where to use these functions.

It's important to understand the difference between sanitizing and validating user data, escaping data for storage, and escaping data for presentation.

##Sanitizing and Validating User Data

When users submit data, you need to make sure that they've provided something you expect.

Easing functions specify the rate of change of a parameter over time.

Objects in real life don’t just start and stop instantly, and almost never move at a constant speed. When we open a drawer, we first move it quickly, and slow it down as it comes out. Drop something on the floor, and it will first accelerate downwards, and then bounce back up after hitting the floor.

This page helps you choose the right easing function.

#Data Validation

Untrusted data comes from many sources (users, third party sites, your own database!, ...) and all of it needs to be validated both on input and output.

PHP Sanitizing filters

List all filters available with your version of PHP

PHP Filters for validation and sanitization are activated by passing at least two values to the PHP Filters Extension function filter_var. As an example, let's use the Sanitize Filter for an Integer number like so:

$value =  '123abc456def';
echo filter_var($value, FILTER_SANITIZE_NUMBER_INT);

In the example, we have a variable $value that is passed through the Filters Extension function filter_var using the FILTER_SANITIZE_NUMBER_INT filter. This results in the following output:

$content = get_the_content($more_link_text, $stripteaser, $more_file);

$content = str_replace(']]>', ']]&gt;', $content);
