The code i personly use is:

//Get the varible P from url
$p = $HTTP_GET_VARS['p'];
// if p does not exist include start page
if(!$p){
include("page_dir/start.php");
}
else
{
// if p is set we see if the document it contains exists, if so we include it
if(file_exists("page_dir/$p.php"))
{
include("page_dir/$p.php") ;
}
else
{
// if it doesnt exist we include the start page
include("page_dir/start.php");
}
}
