Version

The first thing you might want to do is visualize your directory structures. Fat-Free gives you total control over your Web site. Organize your folders in any way that pleases you (or your development team if you're part of a group). Decide where you want to store the following:

• Application and code libraries
• HTML templates
• Graphics and media files
• Javascript and CSS files
• Database (if you plan to use an embedded DB like SQLite)
• Configuration files
• Uploads/Downloads

For security reasons, consider relocating the lib/ folder to a path that's not Web-accessible. If you decide to move this folder, just change the line in index.php containing require 'lib/base.php'; so it points to the new location. The lib/ folder also contains framework plug-ins that extend F3's capabilities. You can change the default location of all plug-ins by moving the files to your desired subdirectory. Then, it's just a matter of pointing the PLUGINS global variable to the new location. You may delete the plug-ins that you don't need. You can reinstate them later as you find necessary.

F3 can autoload OOP classes for you. Just add the path to the AUTOLOAD variable.

When you're ready to write your F3-enabled site, you can start editing the rest of the code contained in the index.php file that displayed this Web page. Developing PHP applications will never be the same!

PHP Dependencies

Some framework features in this version will not be available if PHP is not configured with the modules needed by your application.

Class/Plug-in	PHP Module
	onclick="return false">

• The Base class requires all listed PHP modules enabled to function properly.
• The Cache class will use any available module in the list. If none can be found, it will use the filesystem as fallback.
• The DB\SQL class requires the pdo module and a PDO driver relevant to your application.
• The Bcrypt class will use the mcrypt or openssl module for entropy generation. Otherwise, it employs a custom random function.
• The Web class will use the curl module for HTTP requests to another server. If this is not detected, it will use other transports available, such as the HTTP stream wrapper or native sockets.
• The geoip module listed in the Web\Geo class is optional; the class will use an alternative Web service for geo-location.
• Other framework classes in the list need all its listed modules enabled.

Need Help?

If you have any questions regarding the framework, technical support is available at https://groups.google.com/forum/?fromgroups#!forum/f3-framework

You can also join our Slack Channel to get support

Need live support? You can talk to the development team and the rest of the Fat-Free community via IRC. We're on the FreeNode (chat.freenode.net) #fatfree channel. If the channel appears quiet, the development team might just be busy with the next great release, or it's probably due to time zone differences. Just hang around.

The User Reference is designed to serve as a handbook and programming guide. However, the online documentation at https://github.com/bcosca/fatfree provides the latest and most comprehensive information about the framework.
