The PHP way:
function convertIntegerToIpv4($integer)
{
$max_value = pow(2,32); //4,294,967,296
$bug_fix = 0;
settype($integer, float);
if($integer > 2147483647) $bug_fix = 16777216;
if(is_numeric($integer))
{
if ($integer >= $max_value || $integer < 0)
{
return ('Not a valid IPv4 integer');
}
$ip = (sprintf("%u.%u.%u.%u",
$integer / 16777216,
(($integer % 16777216) + $bug_fix) / 65536,
(($integer % 65536) + $bug_fix / 256) / 256,
($integer % 256) + $bug_fix / 256 / 256
)
);
return($ip);
}
else {
return('');
}
}
