This is what I do:


in all files I have as the first line:

require_once("_startup.php");

then in the file _startup.php I have:

$expiry = 60 * 60 * 24 * 1000;
ini_set('session.cache_limiter', 'nocache');
ini_set('session.use_trans_sid', 1);
ini_set('arg_separator.output', "&amp;");
ini_set('session.use_cookies', 1);
ini_set('session.use_only_cookies', 0);
ini_set('session.cookie_lifetime',
$expiry);//session_set_cookie_params($expiry);
session_start();
setcookie("CookieTest", "t");
ob_start("trimmer");

function sid($withamp) {
if($_COOKIE["CookieTest"] == "t") {
return '';
}
setcookie("CookieTest", "t");
$s = session_id();
if($withamp) {
$v = '&amp;';
}
$v .= 'PHPSESSID='.$s;
return $v;
}

Then for any links within my site, I have (e.g.)
echo '<a href="mylink.php?'.sid(false).'">click here</a>';
echo '<a href="mylink.php?a=2'.sid(true).'">or click here</a>';

works a treat - I am able to track my visitors, I dont have the annoying
session IDs in the URLs, except for people without cookies, however, most
importantly, I dont have to add anything to my files except the require_once
line.

Having said that, I am a bit of a cowboy in the PHP arena, so you may want
to wait until someone tells us that is all wrong ;-)
