Creating the folder structure

As we did in the previous chapters, we will first create the folder structure.

1. Create a folder named Chapter5 inside the MasteringjQueryUI folder.
2. Copy the js and css folders from the downloaded jQuery UI folder inside the Chapter5 folder.
3. Inside the Chapter5 folder, create a PHP file named colorCAPTCHA.php for the first CAPTCHA.

   Note

   Since we are using PHP as server-side language, you will need PHP installed on your machine along with a web server, such as Apache, to run these files. You can use a software bundle, such as WAMP or XAMPP, to install all at one go.
