Visitors Online - With PHP (no MySQL is needed)

FaLgoR
Another script, which shows the visitors onlineat the moment in your site. This script was not made by me, I just think it will be very usefull to u.

CODE

<?
$timeout = 15; // change it. It is the timer which will delete the member of  online list (in minutes)
if (!$datei) $datei = dirname(__FILE__)."/online.txt";
$time = @time();
$ip = $REMOTE_ADDR;
$string = "$ip|$time\n";
$a = fopen("online.txt", "a+");
fputs($a, $string);
fclose($a);
$timeout = time()-(60*$timeout);
$all = "";
$i = 0;
$datei = file("online.txt");
for ($num = 0; $num < count($datei); $num++) {
$pieces = explode("|",$datei[$num]);

 if ($pieces[1] > $timeout) {
  $all .= $pieces[0];
  $all .= ",";
 }
$i++;
}

$all = substr($all,0,strlen($all)-1);
$arraypieces = explode(",",$all);
$useronline = count(array_flip(array_flip($arraypieces)));

echo $useronline;

$dell = "";
for ($numm = 0; $numm < count($datei); $numm++) {
$tiles = explode("|",$datei[$numm]);
 if ($tiles[1] > $timeout) {
  $dell .= "$tiles[0]|$tiles[1]";
 }
}
if (!$datei) $datei = dirname(__FILE__)."/online.txt";
$time = @time();
$ip = $REMOTE_ADDR;
$string = "$dell";
$a = fopen("online.txt", "w+");
fputs($a, $string);
fclose($a);
?>


Now, just make an blank file called online.txt. That's all! I hope I've helped you wink.gif

great script. works like a charm. The only thing I did to it was add a "Most users ever online"

O, and I guess I'll give you rep for it.. you seem to have been very helpful with php for many other users.

I think i used to see the script at hotscripts.com but that's so good when you brought it here.
Anyways on the code "$ip = $REMOTE_ADDR;" wasn't included for share internet but if you want to check for share ip...
Try this...

if ($_SERVER['HTTP_CLIENT_IP']) {
$ip $_SERVER['HTTP_CLIENT_IP'];
} elseif (ereg("[0-9]",$_SERVER["HTTP_X_FORWARDED_FOR"] )) {
$ip $_SERVER["HTTP_X_FORWARDED_FOR"];
} else {
$ip $_SERVER["REMOTE_ADDR"];
}

detecting huh.gif did you mean that code?
OK, guy. i will tell you..

if you use "$ip = $REMOTE_ADDR;" code then go to internet cafe and open your website from 2 computers in there, your web will show only 1 number of user online unsure.gif . But if you use my code the number are 2 online users wink.gif .

Hey thanks that works great, remember you may want to chmod the online.txt page to read and write I believe that is 666 if my memory serves me right. Also another helpful tip. Instead of putting all that in your page use the include funtion.

<? Include("filename.php") ?> Just put that in your main site and save the large piece of coding into filename.php.......

@time= show time
$REMOTE_ADDR = show visitor IP
$string = have $REMOTE_ADDR and @time
$a = fopen("online.txt", "a+"); = open flat file
fputs($a, $string); = write $a and $string string at file
fclose($a); = close file
nice script
really nice
i write this post for help to learn php
but i know very low about php blink.gif

Could you share the code for "most users ever online" here? smile.gif

and yea, simplicity is the key here, love the script!

i just wanna remind everyone that using this script (which uses a flat file) is not recommended if your site has a high overhead. as it will have undesirable effects. your script may not open a file pointer since it is already opened by another. and will render the script useless. if your site has a high overhead, i suggest to migrate to sql.
