How would I express this correctly?
...
elseif ($row_rs['loggedinip'] != $_SERVER['REMOTE_ADDR'] AND now("Y-m-d
H:i:s") < $row_rs['lastlogin']+120 minutes) {
die(header("Location: http://domain.com/login.php")); }
else {...

You should not need the die command if you are redirecting someone at that point if the script fails.

this part in itself... how do I write this correctly?

if ($row_rs['loggedinip'] != $_SERVER['REMOTE_ADDR'] AND now("Y-m-d H:i:s") < $row_rs['lastlogin']+120 minutes) {

If it has to be done in PHP, use Unix Timestamps for the calculation.
Turn the date in $row_rs['lastlogin'] into such a timestamp with
strtotime(). The current timestamp can be obtained with time(). Doing
the math should be quite simple then.

Its not on a unix system
mysql data is in a datetime format

>Its not on a unix system

Doesn't matter. Unix timestamps also work on Windows, they are just one
way to store a time code withing the range of (roughly) 1902-2038.

>mysql data is in a datetime format

You could also let MySQL already return the date as a Unix timestamp or
even do the entire calculation in MySQL, as already suggested. You could
let MySQL return both: the normal 'lastlogin' field and another one with
'lastlogin'+120 minutes or whatever. Or do the entire date test in SQL
and just return a boolean value if the last login was more than 120
minutes ago or not ... there are several different ways.

i understand the theory, but id appreciate a snippet of code

i'm trying to read between the lines and I understand your theory, but I'm not
having much luck with implementing it.

for example:

elseif ($row_rs['loggedinip'] != $_SERVER['REMOTE_ADDR'] AND time() <
date('Y-m-d',strtotime($row_rs['lastlogin']+120 minutes) {

this doesn't work. The datetime is stored in the database as Y-m-d H:i:s

is this right?

elseif ($row_rs['loggedinip'] != $_SERVER['REMOTE_ADDR'] && getdate() < (strtotime($row_rs['lastlogin']+120))) {

elseif ($row_rs['loggedinip'] != '204.9.76.12' && date('Y-m-d H:i:s', strtotime('now')) < date('Y-m-d H:i:s', strtotime("+2 minutes", strtotime($row_rs['lastlogin'])))) {
