phpwind：

if($_SERVER['HTTP_X_FORWARDED_FOR']){
    $onlineip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    $c_agentip=1;
} elseif($_SERVER['HTTP_CLIENT_IP']){
    $onlineip = $_SERVER['HTTP_CLIENT_IP'];
    $c_agentip=1;
} else{
    $onlineip = $_SERVER['REMOTE_ADDR'];
    $c_agentip=0;
}

disuz：

if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
    $onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
    $onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
    $onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
    $onlineip = $_SERVER['REMOTE_ADDR'];
}
