In general source is presented by simply making the original files text files. You can click on the links to see the raw source, or you can right-click to download the files. To use these files you would need to rename them with the appropriate extension(s). For instance, a PHP source file named "fn.txt" needs to be named "fn.php" or "fn.php3" to run on your own server. The extension is dependent on your server's configuration.
PHP Source Code from this SiteIf you want more detailed information about functions you see in these files you can refer to the primary PHP site https//www.php.net/.
If you are interested in how MySQL and PHP work together you might consider looking at https//www.mysql.org/. This web site was built using the LAMP (Linux/Apache/MySQL/PHP) concept. O'Reilly's LAMP site at https//onlamp.com/ is a good resource.
