I set this up using a text file but you'll get the idea save the the
last ip in a field in your database and if the current ip matches the
last one then its the same person and no count is registered. I already
now this works because I'm using it.
$ip = getenv("REMOTE_ADDR");
if ($ip != $data[6]) {
$dstamp = date(Ymd);
$wstamp = date(Ymd,mktime(0,0,0,date("m"),date("d")+(7 -
date(w)),date("Y")));
if ($data[4] < $dstamp) {
$data[2] = 0; $data[4] = $dstamp;
}
if ($data[5] < $wstamp) {
$data[3] = 0; $data[5] = $wstamp;
}
$data[1]++; $data[2]++; $data[3]++;
$fp = fopen($file, "w+");
flock($fp, 2);
fputs($fp,
"$data[0]|$data[1]|$data[2]|$data[3]|$data[4]|$data[5]|$ip");
flock($fp, 3);
fclose($fp);
}
