our tutorial.As in the above code, I have created the method // validate an integer $number = Input::int($_POST['number']); // validate a string $name = Input::str($_POST['name']); // convert to boolean $bool = Input::bool($_POST['boolean']); // validate an email $email = Input::email($_POST['email']); // validate a URL $url = Input::url($_POST['url']); function was described with it's filters with examples.The PHP filter extension has many of the functions needed for checking user input, and is designed to make data validation easier and quicker.The function to check if the variable $int is an integer.

You can copy the above code to a new file and include that file in your script.

If $int is an integer, the output of the code below will be: "Integer is valid".

Check each filter to see what options and flags are available.

The reference contains a brief description, and examples of use, for each function!

This method can be used to validate any integer value such as a primary integer key (user Id, group Id, etc.) in database, timestamp, etc.
