Description:
------------
socket_bind() function on Apache2/ Win2k can't bind

Reproduce code:
---------------
$dest="127.0.0.1";
$port=80;
//"daemon" in UDP
$socketD = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); 

if($socketD === FALSE) { // something went wrong
       echo 'socket_create failed: '.socket_strerror(socket_last_error())."\n";
       exit(1);
   } 
   /*
   This is the second option but still doesn't work
   if(!socket_bind($socketD, "0.0.0.0", 27123)) 
   */
   if(!socket_bind ($socketD, 0, $port))
   {
   socket_close($socketD);
   echo 'socket_bind failed: '.socket_strerror(socket_last_error())."\n";
    exit(1);
   }

Expected result:
----------------
This is the PHP error message:
Warning: socket_bind() [function.socket-bind]: unable to bind address [0];

I realy dug into the documentations and examples and find it hard to believe that I do something wrong. The warning message explains that the socket it already binded and cannot be used twice :((
