PHP：如何检查脚本调用程序的IP地址

Question

I need to add an if statement on top of my php script in order to check the ip of the script invoker:

if (invoker_ip = "123.123.123.123") {
    .. code here ..
}

the script is just a script.php file on my server

Answer 1

$ip = '123.123.132.132';

if ($_SERVER['REMOTE_ADDR'] === $ip) {
    // This will only excexuted if the IP matches
    echo 'IP does match :)';
} else {
    echo 'IP does not match!';
}

Answer 2

invoker_ip = $_SERVER['REMOTE_ADDR']

Answer 3

询问$ _SERVER ['REMOTE_ADDR']，但要小心代理。

Answer 4

Use :

$invoker_ip = $_SERVER['REMOTE_ADDR'];

Nevertheless this value will not be relevant if user is behind a proxy. The real ip probably can be found in HTTP header like HTTP_CLIENT_IP or HTTP_X_FORWARDED_FOR but can't be trusted. (header are easy to modify)
