Question

I’m trying to find a way to set a cookie that sets a user’s IP and passes it to a second page displaying that IP. I’m probably missing something very small, but I’ve tried a few methods.

setcookie('user_ip', $_POST['user_ip']);

I should be able to use this function as well to find the IP, or is there another method that’s easier to use?

server($REMOTE_ADDR);

I keep getting errors with whatever method I use. I just know I’m missing something small.

Answer 1

setcookie('user_ip', $_SERVER['REMOTE_ADDR']); 

Addition:
To echo the IP on the next page, use

echo $_COOKIE['user_ip'];
