IP Logger

[ReidE96]

A simple little PHP script to log IPs along with a datestamp of when they were logged. Yep, that simple.

<?php
    $file_name = ('./ip_log.txt');
    $time = date("d/m/Y h:i A" ,time());
    $ip = $_SERVER['REMOTE_ADDR'];
    $fp = fopen($file_name, "a");
    fwrite($fp, "IP: ".$ip." - Time: ".$time."\n");
    fclose($fp);
?>

If you want to be a LITTLE fancier, you can make it deny access to the file when they try and access it.

<?php
    $file_name = ('./ip_log.php');
    $time = date("d/m/Y h:i A" ,time());
    $ip = $_SERVER['REMOTE_ADDR'];
 
    if(!file_exists($file_name)){
    $fp = fopen($file_name, "w");
    fwrite($fp, "<?php die('Oi! This file is private! No peeking!');?>");
    fclose($fp);}
 
    $fp = fopen($file_name, "a");
    fwrite($fp, "IP: ".$ip." - Time: ".$time."\n");
    fclose($fp);
?>

Enjoy!

I dont have a need for this nor do I really get it, But I know it will be useful for some people :P +rep

[2dgreengiant]

I did need this haha thanks <3

[ReidE96]

I know you needed it, 2d Hence why it was written, then you didn't need it any more lol.

I like it +Rep but maybe should make it so it inserts it into a db I will come back with a edit on how to do it .

[ReidE96]

I could change it to write to a DB, but that would take a little bit more time. Not much, but a little. This is just a quick script thrown together in a few minutes. Though it could be useful if your host didn't give you a db.

[bsod-staff14]

True true . But I was talking in the case of security purposes for a website

[ReidE96]

There's merits to both ways. DB for security, file for less needs.

[bsod-staff14]

Gawd beat me again :P.

Well, not that bad script, but could be done better. I would do it like this:

I would store IP as long int and time as standard time, so it's more flexible and faster to transform in the output. Storing as int makes the script faster because having number takes less memory space than having a string.

    //well, this should bypass proxies and stuff in theory, didn't try in RL :P
    if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")) $ip = getenv("HTTP_CLIENT_IP");
    elseif (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")) $ip = getenv("HTTP_X_FORWARDED_FOR");
    elseif (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")) $ip = getenv("REMOTE_ADDR");
    elseif (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) $ip = $_SERVER['REMOTE_ADDR'];
    else $ip = "unknown";
    
    //we'll store IP as long int, so we can store it as a number into the database
    if ($ip != "unknown")
        $ip = ip2long($ip); //we transform ip from something like 127.0.0.1 to something like 2130706433
        die("Could not retrieve IP."); //we certainly don't want someone with no visible IP to be on our page, so we "die"
    
    $query = 'INSERT INTO log(ip, time) VALUES ('.$ip.', '.time().')';
    mysql_query($query) or die(mysql_error().'<br />'.$query); //we insert values to database or die with error

Inzenir,
you should think of,
(sanitize,)-(secure mysql queries),
and also u should read up on how to stack your code,

if,
elseif
elseif
elseif
else

first of all you could use switch instead.

just saying.

haha nice one :-D Might going to use this logger for my website. Just in a pimped version :-D

Fine piece of work, but another way to make sure people doesn't read it would be to set the permission of the file to 660. Either by using chmod(), or just ftp.
Another way to do it, would be to throw in a 404 header error followed by an exit

<?php
header("HTTP/1.0 404 Not Found");
exit;
?>
