Time stuff calculating with time

[The1corrupted]

I need help with this little time function. After thirty minutes, I want an echo to occur...

[PHP]
$_SESSION['idlemin']=date(i); //This makes the session update each time the page is refreshed but was defined on log in.
$minutes=date(i ); //Current
if ($_SESSION['idlemin']>=$minutes+30 ) {
echo "Your time is up!";
}
[/PHP]

Now, I know this doesn't work for obvious reasons...
Say you logged in at 14:49 well, it would have to equal 14:79 to work and well, time isn't calculated that high so I need something that can spill over hours..

Taking the server time use the strtotime function, e.g.

[php]echo "30 minutes from now = " . date("H:m:s", strtotime("+30 minutes"));[/php]

Tiny syntax error though...
[PHP]date("H:m:s", strtotime("+30 minutes"))[/PHP]
should be
[PHP]date("H:i:s", strtotime("+30 minutes"))[/PHP]

Sorry, my mistake. That's what you get when trying to do it without looking at the manual.

Another quickie on time.. could you compare times?
[PHP]
$idletime=$_SES SION['idle'];
if (date("H:i:s")> =$idletime) {
echo "<META HTTP-EQUIV='refresh' content='0; url=idleout.php '>";
} elseif (date("H:i:s")< =$idletime) {
$idletime=date( "H:i:s", strtotime("+30 minutes"));
}
[/PHP]
And on a different page...
[PHP]$_SESSION['idle']=date("H:i:s", strtotime("+30 minutes"))[/PHP]

Why would you format the timestamp in this case. It would be sufficient to just use the Unix timestamp and calculate and compare with that. The format makes it rather difficult.

Do you mean that gigantic interger gotten when you use the $_SERVER['request_time'] function?

[ronverdonk]

It is just the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).

But yes, that is the time format I mean. In your case the 30 minutes is just 1800 seconds.

Actually, I've found what I wrote to work perfectly fine, suprisingly.. Just changed minutes to seconds for the test and it works.

When it works: stick with it.
