Clean urls fix.

[creptor]

In some cases php error is activated by default (or to search for issues) and you'll find that the clean url script has some errors when all the data is not entered and can cause confusion.

The best solution is to fix it, so the querys just work when there's data associated to the url... example:

http://localhost/user/matthew/edit?language=en&hobbies=art&sport=football

• returns no erros

http://localhost/home

• returns some undefined offsets

To fix this just replace your clean url script with this

function get_path(){
    $path=array();
    if(isset($_SERVER['REQUEST_URI'])){
        $request_path=explode('?',$_SERVER['REQUEST_URI']);
        $path['base']=rtrim(dirname($_SERVER['SCRIPT_NAME']),'\/');
        $path['call_utf8']=substr(urldecode($request_path[0]),strlen($path['base'])+1);
        $path['call']=utf8_decode($path['call_utf8']);
        if($path['call']==basename($_SERVER['PHP_SELF'])){
            $path['call']='';
        }
        $path['call_parts']=explode('/', $path['call']);
        if(array_key_exists(1,$request_path)){
            $path['query_utf8']=urldecode($request_path[1]);
            $path['query']=utf8_decode(urldecode($request_path[1]));
            $vars=explode('&',$path['query']);
            foreach($vars as $var){
                $t=explode('=',$var);
                if(array_key_exists(1,$t)){
                    $path['query_vars'][$t[0]]=$t[1];
                }
            }
        }
    }
return $path;
}

Is the same code with just a check right before the arrays, just tested and works
