從file_get_contents獲取數據，如果“ Y”則重定向

Question

我在PHP中仍然是新手。 我想重定向用戶，如果來自http://www.shroomery.org/ythan/proxycheck.php?ip=xxxxxx的數據為Y，並且如果為N，則什么也不做。我在下面有此代碼。 不知道是否正確。 那我下一步該怎么辦？

<?PHP
// Function to get the client ip address
function get_client_ip() {
    $ipaddress = '';
    if ($_SERVER['HTTP_CLIENT_IP'])
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if($_SERVER['HTTP_X_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if($_SERVER['HTTP_X_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if($_SERVER['HTTP_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if($_SERVER['HTTP_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if($_SERVER['REMOTE_ADDR'])
        $ipaddress = $_SERVER['REMOTE_ADDR'];
    else
        $ipaddress = 'UNKNOWN';

    return $ipaddress;
}


$userIP=get_client_ip();

$xml = file_get_contents("http://www.shroomery.org/ythan/proxycheck.php?ip=$userIP");


?>

謝謝。

就像是，

if( $xml === 'Y' )
    header('Location: http://www.something.com');
