function getip(){

if (getenv("http_client_ip") && strcasecmp(getenv("http_client_ip"), "unknown"))

$ip = getenv("http_client_ip"); //开源

else if (getenv("http_x_forwarded_for") && strcasecmp(getenv("http_x_forwarded_for"), "unknown"))

else if (getenv("remote_addr") && strcasecmp(getenv("remote_addr"), "unknown"))

else if (isset($_server[@#remote_addr@#]) && $_server[@#remote_addr@#] && strcasecmp($_server[@#remote_addr@#], "unknown"))

//

$ip = $_server[@#remote_addr@#];
