122 CHAPTER 4 ■ BUILD AN EVENTS CALENDAR PUBLIC AND NONPUBLIC FOLDERS—WHY BOTHER? You may be asking yourself right about now, “Why put in the extra effort to create public and nonpublic folders? What's the benefit?” To answer that question, you need to know a little bit about how web servers work. A server is essentially a computer that stores files and serves selected files to a network (such as the World Wide Web) using a network identifier (an IP address or a URL mapped to an IP address). Hundreds of web sites or other applications can be hosted on one server, each in their own folder. The server grants access to outside users to these public folders, which means all the files on the folder can be accessed from the network to which the server is connected. In the case of files that contain sensitive information, this isn’t always desirable. Fortunately, files in a public folder can still access files outside of the public folder, even though the users on the network cannot. This allows you to hide your sensitive data from the rest of the world, but keep it accessible to your application. There are other ways to hide this information, but simply keeping sensitive data nonpublic is the most straightforward, surefire method of doing so. Modifying the Development Environment Because you’re using public and nonpublic folders for this application, a quick modification to your development environment is necessary: you need to point the server to your public folder, rather that the folder containing both. In this section, you’ll learn how to point your server to the public folder. ■ Note You can skip this section and keep the sys folder inside the public folder without losing any functionality in the application (keep in mind that file paths will differ from those used throughout the exercises in this book). You will, however, open the application to potential security risks. It’s highly recommended that you take a minute to follow these steps. Local Development To change the document root (public folder) in a local installation, you need to modify the server’s configuration file. This book assumes Apache is being used as your server in the XAMPP stack, so you need to locate the httpd.conf file (located at /xamppfiles/etc/httpd.conf on Mac, /opt/lampp/etc/httpd.conf on Linux, and \xampp\apache\conf\httpd.conf on Windows). Inside httpd.conf, search for the DocumentRoot directive. This is where you set the path to your public folder. The file should look something like this:
# # DocumentRoot: The directory out of which you will serve your # documents. By default, all requests are taken from this directory, but # symbolic links and aliases may be used to point to other locations. # DocumentRoot "/Applications/XAMPP/xamppfiles/htdocs/public" CHAPTER 4 ■ BUILD AN EVENTS CALENDAR Additionally, search for a line in your httpd.conf file that references document root to set permissions. It will look something like this: After locating and altering the paths above, restart Apache using the XAMPP control panel. Now, the default folder accessed is the public folder of the application. To test this, create the file index.php and add the following code snippet:
