Thank you Abhas for sharing your resource
I am not much into Web development and programming but after going through your code i think using this code we can get number of online users who are surfing our website, Right ?
If 'Yes' where should i put above code [ which directory ] so that i can get/show current traffic details for my website.

Hello Harry your question regarding where should i put that?

By default all forums have a who is onlie page

for example your online page would be

http://www.webhosting.uk.com/forums/online.php

If your wanting to know if you could put that on your main website you could but also think of the vulnerabilities as well

this script displays ips

$ip = getenv("REMOTE_ADDR");

i would rather use http script than the getenv one

you will be taking a risk of helping malicious users gain viewable and live computers ips

which is a major security risk


but the file here would be called

if(!file_exists($file_name))

where file_name = what you want it to be

i do hope this helps if im wrong im very sorry
