Here is a function a found on php.net that turns the IP.
Everything that Justin said is true too. If they have a dial-up user or are
behind a proxy server you can't track them.
Also if you are saving this to a database table it will get very big fast,
just like Justin said. I would create a table just for today's hits, then
have a script run at 12:01 everyday that creates a summary record and saves
it to another table. Then delete the records from the today hits. You
could setup a crontab to run the script for you.
function getip() {
if (isSet($_SERVER)) {
if (isSet($_SERVER["HTTP_X_FORWARDED_FOR"])) {
$realip = $_SERVER["HTTP_X_FORWARDED_FOR"];
} elseif (isSet($_SERVER["HTTP_CLIENT_IP"])) {
$realip = $_SERVER["HTTP_CLIENT_IP"];
} else {
$realip = $_SERVER["REMOTE_ADDR"];
}
} else {
if ( getenv( 'HTTP_X_FORWARDED_FOR' ) ) {
$realip = getenv( 'HTTP_X_FORWARDED_FOR' );
} elseif ( getenv( 'HTTP_CLIENT_IP' ) ) {
$realip = getenv( 'HTTP_CLIENT_IP' );
} else {
$realip = getenv( 'REMOTE_ADDR' );
}
}
return $realip;
}
