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

Answer 1

As all others said before you can use $_SERVER['REMOTE_ADDR']; to get the client IP address.

Also, if you need more information about a user, you can use this:

" . $clientDetails->country . "";
?>

Client's more specific information goes in $clientDetails.
You can fetch JSON items stored in $clientDetails variable this way: $clientDetails->PostalCode/hostname/region/loc...

I'm using ipinfo.io to get extra information.
