PHP switch with GET request

Question

I am building a simple admin area for my site and I want the URLs to look somewhat like this:

http://mysite.com/admin/?home
http://mysite.com/admin/?settings
htt         


        

Answer 1

You can make your links "look nicer" by using the $_SERVER['REQUEST_URI'] variable.

This would allow you to use URLs like:

http://mysite.com/admin/home
http://mysite.com/admin/settings
http://mysite.com/admin/users

The PHP code used:

// get the script name (index.php)
$doc_self = trim(end(explode('/', __FILE__)));

/*
 * explode the uri segments from the url i.e.: 
 * http://mysite.com/admin/home 
 * yields:
 * $uri_segs[0] = admin
 * $uri_segs[1] = home
 */ 

// this also lower cases the segments just incase the user puts /ADMIN/Users or something crazy
$uri_segs = array_values(array_filter(explode('/', strtolower($_SERVER["REQUEST_URI"]))));
if($uri_segs[0] === (String)$doc_self)
{
    // remove script from uri (index.php)
    unset($uri_segs[0]);
}
$uri_segs = array_values($uri_segs);

// $uri_segs[1] would give the segment after /admin/
switch ($uri_segs[1]) {
    case 'settings':
        $page_name = 'settings';
        break;
    case 'users':
        $page_name = 'users';
        break;
    // use 'home' if selected or if an unexpected value is given
    case 'home':
    default: 
        $page_name = 'home';
        break;
}
