Bug description: long2ip problems with unsigned double
When storing ips as unsigned doubles I noticed a strange behaviour when
passing unsigned doubles through the long2ip routine.
-- sample --
<?php
$ip = ip2long("192.168.0.1");
print long2ip($ip)."\n";
if ($ip < 0) $ip+=pow(2,32); //convert from signed to unsigned
print long2ip($ip)."\n";
?>
-- end ---
In the first line - as supposed - the script returns "192.168.0.1", but
after conversion I get an offset by one and it returns "192.168.0.0". I
read in the doc that long2ip is capable of handling both signed and
unsigned long integers.
