Writing, Removing, Timeouts, Complicated Stuff

[xwin]

Alright, I'm having some trouble (haven't been here in awhile). I'm trying to make a 'Users Online' type thing.

I want guests and members to appear. Here's the code I have. I've been studying it for awhile. It outputs no errors, but I have a funny feeling it isn't fwriting any of the data.

$timeout and $userid are defined elsewhere, but they are there.

$timestamp = time();
$old = $timestamp - $timeout;
// time to bust out the users online file
$users_online = fopen("data/users_online.txt","a");
fwrite($users_online, "$timestamp|$REMOTE_ADDR|$PHP_SELF|$userid|");
fclose($users_online);

$read = file("data/users_online.txt", "r");
foreach ($read as $read_line)
{
$buffer = explode("|", $read_line);
$stamps[] = trim($buffer[0]);
$ip[] = trim($buffer[1]);
$phpself[] = trim($buffer[2]);
$uid[] = trim($buffer[3]);
}

$users_online = fopen ("data/users_online.txt", "w");
flock ($users_online,2);
for ($x = 0; $x < sizeof($ip); $x++)
{
if ($stamps[$x] > $old && $ip[$x] != $REMOTE_ADDR && $stamps[$x] != $timestamp)
	fputs($users_online, "$stamps[$x]|$ip[$x]|$phpself[$x]|$uid[$x]|");
flock ($users_online,3);
fclose($users_online);

$read = file("data/users_online.txt","r");

foreach ($read as $read_line)
{
if(isset($read_line) && $read_line!="")
	{
	        $buffer = explode("|", $read_line);
                $stamps[] = trim($buffer[0]);
                $ip[] = trim($buffer[1]);
                $phpself[] = trim($buffer[2]);
                $uid[] = trim($buffer[3]);
                        if($buffer[3] != "")
                                $uid2[] = trim($buffer[3]);
        }
}

$total_online = sizeof(array_unique($ip));
if(isset($uid2)) $members_online = sizeof(array_unique($lname2)); else $members_online = 0;
if(isset($lname2)) $guests_online = sizeof(array_unique($ip)) - sizeof(array_unique($uid2));
else $guests_online = sizeof(array_unique($ip));
}

See, this is what happens. It displays 1 guest, 0 members no matter how many people are at the page. I think it's just displaying everyone as guest, but not writing that data to the file, which it should. So it only shows 1 guest.

I'm kinda brainlocked on this one. Anyone can help me?

BTW, users_online.txt is CHMODDED to 0777, so that isn't an issue.

Thanks,

Have you seen your users_online.txt file? I have a suspicion your code is putting all the guests and members into one line, instead of many lines...check out the file.

I don't think it's even writing to the file.

Observe. The homepage of where the script would write you to the file: http://www.quickbb.com/forums

And users online: http://www.quickbb.com/forums/data/users_online.txt

Then I'd suggest you put some if statements before the fwrite to make sure that the file has been opened successfully...
