Logging Users IP

[Sholin]

I'm making a Admin control panel, and I want to log all the IP's that are going to it.... How would I go about doing this?

[killer2239]

If your using mysql then...

$query = "INSERT INTO table (ip) VALUES ('{$_SERVER['REMOTE_ADDR']}')";
mysql_query($query); 

Make sure you have unique ID's for each ip in the table or something like that.

Cool i'll do that once i have my database running, is there some way just to write it to a file right now?

[notepad_coder]

try this, "I think"

$fp = fopen("ips.txt", "a");
fputs($fp, $_SERVER['REMOTE_ADDR']."\r\n");
fclose($fp); 

And that should write each IP on a new line.

Ok try this

<?php

gethostbyaddr($REMOTE_ADDR);
$filename = "rupert.log";
$datearray = getdate();
$year = $datearray["year"];
$month = $datearray["mon"];
$day = $datearray["mday"];
$hour = $datearray["hours"];
$minute = $datearray["minutes"];
$fl=fopen($filename,'a');
fwrite ($fl, "[$month/$day/$year, $hour:$minute] $REMOTE_ADDR");
?>

I hope it works

Rupert your code works great! Thanks!

[Rupert]

Thanks

for that ftp function, couldn't you also use a+? would that make a huge difference? then you could read it, too. right?

The REMOTE_ADDR environment variable will not always contain the IP of the person viewing a page, for example if they use a proxy server. So you should check for the presence of X_FORWARDED_FOR - if it is set, then it will give the real IP of the user if they are using a proxy server.

[Rupert]

X_FORWARDED_FOR is there any other information i could read about. I'm kind of curious about it.

[DR_LaRRY_PEpPeR]

i don't really know of any official place about it. just check to see if it exists, and if it does, i guess use it instead of REMOTE_ADDR. it can, however, be spoofed into anything since it's sent by the client (unlike REMOTE_ADDR). it is sent by the client in the X-Forwarded-For: header and is available in PHP via $_SERVER['HTTP_X_FORWARDED_FOR'].

there are some other ones like HTTP_CLIENT_IP, but i don't know what's used when. i guess it depends on the proxy.
