Newbie Time()

[harvillo]

Okay,

I've been through several tutorials but am still having a (what seems to be) simple issue.

I have a timestamp set in a database for a user:

Say

$original_timestamp=timestamp when the user registered (in database)

I would like to display a message to the user if upon logging in , it has been more than 24 hours since the last login date. Using php.net I think it would be some thing like...

function ago($original_timestamp){
$difference = time() - $original_timestamp;
$difference = round($difference / 60);
if($difference > 24)
return $difference." print it's been greater than 24 hours";
}
}

Is this close?

It's pretty close, but might be easier if you do it another way.

function ago($original_timestamp){
if(time() - $original_time > 86400) // amount of seconds in a day
{
echo "it's been greater than 24 hours";
}
}

Another approche:

/**
 * since u only need to check if 24 hours pass since he's last login
 * then this could be a boolean function
 */
function ago($original_timestamp) {
	if (strtotime("+24 hours",$original_timestamp)>mktime()) return false;
	else return true;
}

/* testing */
$original_timestamp = strtotime("-24 hours");
//$original_timestamp = strtotime("-24 hours 1 seconds");
if (ago($original_timestamp)) {
	echo "It pass more then 24 hours!";
}

Actually, if I understand you, what you are trying to accomplish is not possible the way you are going about it.

What you want to do is find out how long it has been since their "Last Login" (not how long it has been since they "Originally Registered").

In that case, you need to create a new field in your database called: last_login

You will then need to update that field with each successful login.

Then you will be able to do what you want.

Otherwise, you will just continue to find out the amount of time since when they "Originally registered" to the site.... not their last login.
