How to get the client IP address in PHP
Sometimes Webmaster need to know the visitor’s IP address for security purpose. We can easily get the visitor's IP by using $_SERVER variable that is created by the server.
Sometimes $_SERVER variable does not returns the correct IP of the visitor. This can be occur due to reasons like the user is behind a proxy etc. That's why we are using the other server variables to get the IP address.
PHP client IP Example
echo $_SERVER['REMOTE_ADDR'];
echo "or";
$ip = getenv('HTTP_CLIENT_IP')?:
getenv('HTTP_X_FORWARDED_FOR')?:
getenv('HTTP_X_FORWARDED')?:
getenv('HTTP_FORWARDED_FOR')?:
getenv('HTTP_FORWARDED')?:
getenv('REMOTE_ADDR');
echo $ip;
Output
