Visitors Online With PHP (no MySQL is needed)

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.

<?$timeout = 15; // change it. It is the timer which will delete the member of  online list (in minutes)if (!$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

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.

Thank you =]I don't know why I'm tryn to get reputation points, but I like to collect them, just for fun =P

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"];}

what about detecting if they are on something like AOL proxy?

what about detecting if they are on something like AOL proxy?

detecting 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 . But if you use my code the number are 2 online users .

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 filefputs($a, $string); = write $a and $string string at filefclose($a); = close filenice scriptreally nice i write this post for help to learn php but i know very low about php

no9t9Could you share the code for "most users ever online" here? :Dand 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.
