Re: [PHP] MySQl IP Address Storage
Felix,
Just to save you the headache that I encountered, the column that you plan
to store your IP address in needs to be an unsigned integer when using
INET_ATON and INET_NTOA
If it's not, all addresses stored will come out as 127.0.0.0 (I think that
was what it was...).
Also, these are MySQL functions, not PHP functions. Not sure if you knew
that already, but it wasn't specified on the list...
INET_ATON converts from Decimal IP and INET_NTOA converts back to Decimal
IP, so you'd use it like this:
INSERT INTO mytable (ipaddress) VALUES (INET_ATON('192.168.1.1'));
SELECT INET_NTOA(ipaddress) FROM mytable;
Make sense?

INT UNSIGNED
and use the MySQL functions INET_ATON() INET_NTOA() for converting.
If you're on a pre-3.23 MySQL server then:
// Convert IP string (XXX.YYY.WWW.ZZZ) to float and back
function inet_aton($a) {
$inet = 0.0;
// $a=preg_replace('/^[0-9a-f:]*:/', '', $a); // eat IPv6 off the front
$t = explode('.', $a);
while (list(,$i) = each($t)) {
$inet *= 256.0;
$inet += $i;
};
return $inet;
}
function inet_ntoa($n) {
$t=array(0,0,0,0);
$msk = 16777216.0;
$n += 0.0;
if ($n 1)
return('nbsp;');
for ($i = 0; $i 4; $i++) {
$k = (int) ($n / $msk);
$n -= $msk * $k;
$t[$i]= $k;
$msk /=256.0;
};
$a=join('.', $t);
return($a);
}
