Most Users Ever Online

So, I've been using this script to show how many users are currently online:
<?php

$rip = $_SERVER['REMOTE_ADDR'];
$sd = time();
$count = 1;

$file1 = "ip.txt";
$lines = file($file1);
$line2 = "";

foreach ($lines as $line_num => $line)
{
//echo $line."<br>";
$fp = strpos($line,'****');
$nam = substr($line,0,$fp);
$sp = strpos($line,'++++');
$val = substr($line,$fp+4,$sp-($fp+4));
$diff = $sd-$val;
if($diff < 300 && $nam != $rip)
{
$count = $count+1;
$line2 = $line2.$line;
//echo $line2;
}
}

$my = $rip."****".$sd."++++\n";
$open1 = fopen($file1, "w");
fwrite($open1,"$line2");
fwrite($open1,"$my");
fclose($open1);
?>

Could someone show me how to add something into this script that will show how many users was the most ever online? Also, if its not too hard, the date they were online.

Thanks,

Hi x,

Just go through this script and make use of it in your way

Come back for any issues

This is identical to the script I just posted. -_-

I need an ADDITION to that script that will record the most users ever online and display it.
