How can i echo the users who online on my site (who is logged in)..

You would have to do something like store the last active time in a table, update it every page load. And to get the active users do a query to get the users where this time is within 5 minutes.

Ok, and how i can echo time(); to the real time, example: 19:34

date() is used to print a formatted time, is that what you need ?

Look, i think to do design of table like this:

session name, ip adress, lastlogin (including refreshing the page). I after this i think i should do this:

$timelogin = actual time - lastlogin

and if $timelogin > 15 minutes echo nothing, else get from the database all users who logged in for 15 minutes.

Is this correct? Is this the way i should do the "who is logged in"?

That's the basics of it yes.

Huh, i understand it now. Im going to code it, and post it here again, to see is it correct.

Ok, here is the code:

<?php

	$actualtime = date("h:m");
	$query = mysql_query("SELECT * FROM `sf_sessions`");
	
	while ($row = mysql_fetch_assoc($query)) {
		$pastime = $row['lastlogin'];
		
		$timeloggedin = $actualtime - $pastime;
		
		if ($timeloggedin >= 15) {
			echo 'Users logged in for 15 minutes:' $row['sessioname'];
		}
	}

?>

Hmm, you will need to use a timestamp to do the math.

what id the format of the lastlogin column ?

you can probably do it with just one query

SELECT `sessionmame` FROM `sf_sessions` WHERE UNIX_TIMESTAMP() - UNIX_TIMESTAMP(`lastlogin`) < 900

something like that anyway.

Am i going to use timestamps on insert query?

That's up to you It would certainly make the maths easier.

God damn, here is the new problem.
When i put the date like this: date("h:m"); it always repeat same time 09:05..

EDIT: again new problem:

look on the right side of http://brainiac-design.info/probe/sfilms/, i just want to echo one time user, not to repeat.

post your code

Imoporting the users:

$member = $_SESSION['member'];
	if ($member) {
		$time = time();
		$ipadress = $_SERVER['REMOTE_ADDR'];
		mysql_query("INSERT INTO `sf_sessions` (sessionname, ipadress, lastlogin) VALUES ('$member','$ipadress','$time')");
		echo mysql_error();
	}

Echoing the users:

<?php
						$currentime = time();
						$query = mysql_query("SELECT `sessionname` FROM `sf_sessions` WHERE '$currenttime' - `lastlogin` < 900 ORDER by lastlogin desc");
						echo mysql_error();
							if ($query) {
								while ($row = mysql_fetch_assoc($query)) {
								echo $row['sessionname'];
							}
						}
					?>

Are you inserting that row on every page load ? because it should be an UPDATE.

the "ON DUPLICATE KEY UPDATE" syntax may be of use

Thanks good, and also thanks to you. I fixed it.
