<?php 
function get_client_ip() {
    $ip = $_SERVER['REMOTE_ADDR'];
    if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
        $ip = $_SERVER['HTTP_CLIENT_IP'];
    } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    return $ip;
}
echo 'Your IP address is: ' . get_client_ip();
?>


//一般性可以直接使用
<p>Your IP address is: <?php echo $_SERVER['REMOTE_ADDR']; ?></p>
