Can you please post a short script which shows the problem?

Hi Derick.

here is a short code script fpr ip2long().
<?php
$tmp1="192.168.0.10";
$tmp2=ip2long($tmp1);
$tmp3=long2ip($tmp2);
echo "$tmp1 - $tmp2 - $tmp3";
?>

Under php4.0.5 $tmp2 results: -1062731766
with the same compiler options
under php4.0.6RC1 :  3232235530

Not a bug at all, this is the correct way to do it:
<?php
$tmp1="192.168.0.10";
$tmp2=ip2long($tmp1);
$tmp3=long2ip($tmp2);
printf ("%s - %u - %s", $tmp1, $tmp2, $tmp3);
?>
