I've used this function before a couple of times, but I haven't tested
it fully. Give it a go if you want.
/*** BEGIN CODE ***/
// Function get_ip
function get_ip()
{
// List of possible ip sources, in order of priority
$ip_sources = array
(
"HTTP_X_FORWARDED_FOR",
"HTTP_X_FORWARDED",
"HTTP_FORWARDED_FOR",
"HTTP_FORWARDED",
"HTTP_X_COMING_FROM",
"HTTP_COMING_FROM",
"REMOTE_ADDR",
);
foreach ($ip_sources as $ip_source)
{
// If the ip source exists, capture it
if (isset($_SERVER[$ip_source]))
{
// Beware of semicolon seperated lists
$possible_ips = explode(";", $_SERVER[$ip_source]);
// Always take just the first
$proxy_ip = $possible_ips[0];
break;
}
}
// If the ip is still not found, try the getenv() function without
error reporting (may give false)
$proxy_ip = (isset($proxy_ip)) ? $proxy_ip : @getenv("REMOTE_ADDR");
return $proxy_ip;
}
/*** END CODE ***/
