anytime i go on a proxy it just the proxy ip it shows no my ip

[Mystical]

Try this. Not sure if it works but it is worth a shot..

function getRealIpAddr()

{

if (!empty($_SERVER['HTTP_CLIENT_IP']))

{

$ip=$_SERVER['HTTP_CLIENT_IP'];

}

elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))

//to check ip is pass from proxy

{

$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];

}

else

{

$ip=$_SERVER['REMOTE_ADDR'];

}

return $ip;

}

The issue with HTTP_X_FORWARDED_FOR is that you can place it without any problem in the browser header and if your site does look at that, then it may be tricked.

[grant]

the trick is to stop user login on a proxy and if they do it strips the proxy from there ip so that there real ips showing like

before you log please note any proxy on the site have been stripped so its your own ip

and you can no longer hide your ip entering this site

Your ip is ******** to show there own ip but i no some proxy will and cant be strip

[a_bertrand]

Without using a proxy, you can send the HTTP_X_FORWARDED_FOR header and therefore fake the IP.

Also, there is no real good solution to block proxy.

[strangeeyes]

if you block proxys dont you then block mobile phone users ?

Not really, since those are private proxies, and by proxy I mean an implementation of squid and a subnet of IPs.

There are countless other ways to block spam, so don't rely on any "proxy blocker".
