[Tutorial] How to grab IP adress with PHP

[flAmingw0rm]

Hello Support Forums,

In this tutorial I will show you how to grab someone's IP Adress when they visit a website.


The variable to use is $_SERVER['REMOTE_ADDR'] - It's that simple. You can use it for just about anything, here are a few examples.

Printing the Users IP Address:

PHP Code:

<?php 
print ($_SERVER['REMOTE_ADDR'], "I'm Watching You!"); 
?>

Printing it to a File:

PHP Code:

<?php 
$ip = $_SERVER['REMOTE_ADDR']; 
$handle = fopen('ipaddresses.txt'', 'a+); 
fwrite($handle, $ip); fwrite($handle, "\n"); 
fclose($handle); 
?>

Now, you have to make a new text file and insert any of these codes or your own and save it as "anything.php".

Good luck.

Good and easy....
But you should really remove the use of the second fwrite()

PHP Code:

fwrite($handle, "{$ip}\n");

does the {} get printed also? i mean wouldnt the best way just be fwrite($handle, $ip . "\n");

No...
That's useful when you want to use a variable within a string....

PHP Code:

echo "This will print {$var}s and add s on the end :D..."; 


But your way is also fine, I just like the looks of {}..

Code:

$handle = fopen('ipaddresses.txt'', 'a+);

should be

Code:

$handle = fopen('ipaddresses.txt', 'a+');

Code:

$handle = fopen('ipaddresses.txt'', 'a+);

should be

Code:

$handle = fopen('ipaddresses.txt', 'a+');

I can't edit my thread anymore. Anyway, thank you.

How would you exclude a specific IP from being detected?
