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('');
  }
}
