put this code in the home web page
<?php
$timeoutsecs = 900;
$timestamp = time();
$caduc = $timestamp+$timeoutsecs;
$conexion = @mysql_connect("localhost", "user", "password") or die ("No db
CONEXION");
mysql_select_db ("yourdb", $conexion);
mysql_query("INSERT INTO uonline SET " . "caduc='$caduc'," .
"ip='$REMOTE_ADDR'," . "file='$PHP_SELF'");
mysql_query("DELETE FROM uonline WHERE caduc<'$timestamp'");
$result = mysql_query("SELECT DISTINCT ip FROM uonline");
$conn = mysql_num_rows($result);
$dbdecnx = mysql_close ($conexion);
if ($conn==1) {
echo"<span class=\"textPequ\">$conn user online</span>";
} else {
echo"<span class=\"textPequ\">$conn users online</span>";
}
?>
and create this table in you db to hold the necesary values
#
# Table structure for table 'uonline'
#
CREATE TABLE `uonline` (
`caduc` int(15) NOT NULL default '0',
`ip` varchar(40) NOT NULL default '',
`file` varchar(100) NOT NULL default '',
PRIMARY KEY (`caduc`),
KEY `ip` (`ip`),
KEY `file` (`file`)
) TYPE=MyISAM;
