php: ip2long returning negative val

Question

function ip_address_to_number($IPaddress) { 
     if(!$IPaddress) {
      return false;
     } else {
      $ips = split(\'\\.\',$IPaddress);
      return($ips[3] +          


        

Answer 1

Try this instead:

$ip = sprintf('%u', ip2long($_SERVER['REMOTE_ADDR']));

sprintf will then write it as an unsigned integer.
