In a website I was making, I had a rating system in which votes were by unique IP address. It was very easy to retrieve it, yet there are people that may not know so I share it with all of you.
1. In your PHP file, you will obtain the IP from the global array $_SERVER. To obtain the IP we will get ‘REMOTE_ADDR’ and we will save it in a variable:
$ip = $_SERVER['REMOTE_ADDR']; print $ip;
That was easy, right? If you have any questions, comments, suggestions for articles, please do not hesitate to contact me and I’ll be more than glad to assist you.
