Manage URL routes in own php framework

I\'m creating a PHP Framework and I have some doubts...

The framework takes the url in this way: http:/web.com/site/index

It takes the first paramet

I don't use OOP, but could show you some snippets of how I do things to dynamically detect if I'm in a subdirectory. Too keep it short and to the point I'll only describe parts of it instead of posting all the code.

So I start out with a .htaccess that send every request to redirect.php in which I splice up the $_SERVER['REQUEST_URI'] variable. I use regex to decide what parts should be keys and what should be values (I do this by assigning anything beginning with 0-9 as a value, and anything beginning with a-z as key) and build the array $GET[].

I then check the path to redirect.php and compare that to my $GET array, to decide where the actual URL begins - or in your case, which key is the controller. Would look something like this for you:

$controller = keyname($GET, count(explode('/', dirname($_SERVER['SCRIPT_NAME']))));

And that's it, I have the first part of the URL. The keyname() function looks like this:

/*************************************
 *  get key name from array position
 *************************************/
function keyname ($arr, $pos)
{
    $pos--;
    if ( ($pos < 0) || ( $pos >= count($arr) ) )
          return "";  // set this any way you like

    reset($arr);
    for($i = 0;$i < $pos; $i++) next($arr);

    return key($arr);
}

To get the links pointing right I use a function called fixpath() like this:

print 'link';

And this is how that function looks:

/*************************************
 *   relative to absolute path
 *************************************/
function fixpath ($path)
{
    $root = dirname($_SERVER['SCRIPT_NAME']);
    if ($root == "\\" || $root == ".") {
        $root = "";
    }
    $newpath = explode('/', $path);
    $newpath[0] .= $root;
    return implode('/', $newpath);    
}

I hope that helps and can give you some inspiration.
