Advanced Navigation using Includes 0

A very simple way of doing the index.php?page=page_here. Includes a few configuration options.
Written in php4, works in php5, mostly so you can view the source and attempt at understanding how it works.
/*--- Configuration ---*/ $page = Array(); // Edit these vars or leave as is. $page['home'] = "home"; // Replace this with the default or main page. $page['error'] = "404"; // Replace this with the 404 page, can be 'home' also or even $page['home']. $page['format'] = ".php"; // This will be the format of your page so ?page=bla will be bla.php. $page['trig'] = "page"; // The trigger used so ?page=bla. /*--- Do not edit below! ---*/if (empty($_GET[($page['trig'])])) { $pg = $page['home'].$page['format']; } elseif (!ctype_alpha($_GET[($page['trig'])])||!file_exists($_GET[($page['trig'])].$page['format'])) { $pg = $page['error'].$page['format']; } else { $pg = $_GET[($page['trig'])].$page['format']; } include($pg);
ctype_alpha is used to make sure the “page” passed by the user only contains characters A-Z for security (so people can’t include /etc/passwd for example).
file_exists is used to determine whether the page + extension actually exist and if they don’t, the error page is then thrown.
An idea, if you want a readable page name from $pg, you could try
$page_name = ucwords(basename($pg, $page['format']));
