time stamp?

[Anon]

Greetings all,
Ok, what i want to do is take a simple time stamp ($time = date("H:i:s")😉 and compare it to a timestamp cookie. (yes im making my own session) but how can i check if it is above lets say 15 minutes later than the cookie? or has "timed out"?

thanks all

It would be a lot simpler if, instead of storing a formatted string, you stored the real Unix-style timestamp.

Keep in mind that Unix defines a timestamp as the number of seconds since January 1, 1970 at the stroke of midnight GMT.

First, store it:

setcookie("oldtime",time());

Then, on subsequent pages,

$difference = time() - $oldtime;

Now you have a difference value ... in seconds. Do the math:

$difference = difference / 60;

Now you have minutes.

if ($difference > 15) echo "it's been more than fifteen minutes!";
