session_register() doesnt seem to save anything in functions, eg.

session_start();

function bob() {
$var = "somethinghere";
session_register("var");
}

bob();
echo session_encode();

the above only registers the var name, not the data in it.

if it helps theres a way around it, all you gota do is make the $var global so instead of having $var have $GLOBALS['var'] and it works fine.

might be little bug, but it stuffed me up 4 nights in a row.

oh and the way i compiled php was just with apt-get install php4 in debian, (newbie here)

This is not a Bug. All variables that you plan to register must be global!

Reason:
The PHP-function session_register() only  'remember' the *names* of the variables (not the content) it must save when the script terminates.
The session vars are read at script end. This happens outside of any function or methode and therefor only global vars that have been set have a value; all others are unset.

Indeed, not a bug, thx for explaining!. Please also note that you can use this in 4.1.x and higher:
$_SESSION['var'] = 'somethinghere';

It registers the session var 'var', whcih can be accessed through your whole script (in functions, or outside functions) as $_SESSION['var'].
