How to get the client IP address in PHP [duplicate]

Answer 1

Well, this can be simply done by using the GLOBAL variable named as $_SERVER.

The $_SERVER is an array which has the attribute name REMOTE_ADDR.

Just assign it like this:

$userIp = $_SERVER['REMOTE_ADDR'];

Or use it directly like echo $_SERVER['REMOTE_ADDR']; or echo ($_SERVER['REMOTE_ADDR']);.
