subtracting time...

[Perad]

$lastlogin = strtotime($row['last_login']);

$now = strtotime(now);

$difference = date("u", $now) - date("u", $lastlogin);

 

I want to know if there is an hour difference between now and when the user last logged in. How do I do this as I am completely failing when I try to subtract the two with date functions.

the last_login row, is that a datetime field in the database?

[Perad]

yes e.g.  2007-10-08 12:10:47

this does work, although it isnt how i'd do it:

$lastlogin = date("h", strtotime("2007-10-08 08:32:47"));
$now = date("h");
$difference = $now - $lastlogin;

echo $now."<br>".$lastlogin."<br><br>";

echo $difference;
