Get IP Address :

$ip=$_SERVER['HTTP_CLIENT_IP'];

Insert Into Mysql

$ins=mysql_query("INSERT INTO smp_result SET point='$option',ip='$ip', tm='$id'");

Show the result :

$prog=mysql_query("SELECT * FROM smp_result WHERE tm='$id' AND ip='$ip'");

but the stored IP Address is the IP Address of the ISP, what if I want to save the DHCP IP Address ??

Your server can _only_ see the public address of the client. Do you mean to say that you want to store the RFC 1918 address of a client behind a router or NAT for example? Like a `10.0.0.1` or `192.168.1.1` address? – Michael Berkowski Jan 15 '15 at 03:18
`$ip = $_SERVER['REMOTE_ADDR']?:($_SERVER['HTTP_X_FORWARDED_FOR']?:$_SERVER['HTTP_CLIENT_IP']);` – Bender Jan 15 '15 at 03:18
