help with "users online" script

[cornishdubstep]

im not referring to the everyday users online script.

I want a script that can show how many users are on a specific page, but from another page.


its to go on a page showing all the chat rooms, i'd like a code to go next to each room showing how many users are on that page in the room, this way peeps know if anyones in there before they click into it, login and find its empty.... i hope i made more sense with this paragraph, ive searched the net for an answer, no joy yet

cheers

PM me with the chat program and i will see if i can help

[cornishdubstep]

the chat rooms are are java, the script is used for each chat room (chat room being just a page with script).

the page with the list of chat rooms is just a page with simple links to the pages containing this script.

i just want to show the users on each of those pages next to the link

sorry then i can't help you i am not good with java based chat

IMO a php / flash based chat would work better

Maybe this if you have all links on a html/php page: http://cownt.us/

firstly create a file : "online.txt" and chmod permission to 777(read,write,execute)
use this below code.

<?php

function online_users()
{
$log_file = "online.txt";
$min_online = "1";

if ($HTTP_X_FORWARDED_FOR == "")
{
$ip = getenv(REMOTE_ADDR);
}
else
{
$ip = getenv(HTTP_X_FORWARDED_FOR);
}

$day = date("d");
$month = date("m");
$year = date("Y");
$date = "$day-$month-$year";

$ora = date("H");
$minuti = date("i");
$secondi= date("s");
$time = "$ora:$minuti:$secondi";

$users_read = fopen("$log_file", "r");
$users = fread($users_read, filesize("$log_file"));
fclose($users_read);

$to_write ="$ip|$time|$date";
if($users==0)
{
$user_write = fopen("$log_file", "w");
fputs($user_write , $to_write );
fclose($user_write );
}
else
{
$users=explode("\n",$users);
$user_da_tenere=array();

while (list ($key, $val) = each ($users))
{
$user_sing=explode("|",$val);

if($date==$user_sing[2])
{
$h=explode(":",$user_sing[1]);
if($ip!=$user_sing[0])
{
if(($h[0]==$ora)and(($minuti-$h[1])<=$min_online))
{
$user_da_tenere[]=$val;
}
if(($h[0]==($ora-1))and((($minuti+2)-$h[1])<=$min_online))
{
$user_da_tenere[]=$val;
}
}
}
}

$user_da_tenere[] = $to_write;
$user_write = fopen("$log_file", "w");
fputs($user_write , "" );
fclose($user_write );

while (list ($k, $v) = each ($user_da_tenere))
{
$new_file_log = fopen ("$log_file", "a");
fwrite($new_file_log,"$v\n");
fclose($new_file_log);
}
}
$users_online_read = fopen("$log_file", "r");
$users_online = fread($users_online_read, filesize("$log_file"));
fclose($users_online_read);

$users_online = explode("\n",$users_online);
$n_u_online = count($users_online)-1;

return $n_u_online;
}

echo online_users();
?>

Try webdesign.org, they have a php users online but it requires a database.
