1、获得外网的ip代码
function get_online_ip() {
$onlineip = ‘‘;
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‘];
}
return $onlineip;
}
2、获得内网的ip的代码
function getClientIP()
{
$client_ip = null;
if (getenv("HTTP_CLIENT_client_ip"))
{
$client_ip = getenv("HTTP_CLIENT_client_ip");
}
else if (getenv("HTTP_X_FORWARDED_FOR"))
{
$client_ip = getenv("HTTP_X_FORWARDED_FOR");
}
else if (getenv("REMOTE_ADDR"))
{
$client_ip = getenv("REMOTE_ADDR");
}
else
{
$client_ip = null;
}
return $client_ip;
}
