note 19032 added to function.socket-create

Actually, you don't need to use getprotobyname("tcp") but instead can use the constants: SOL_TCP and SOL_UDP. Here an extract of the source from ext/sockets which should make this clear. if ((pe = getprotobyname("tcp"))) { REGISTER_LONG_CONSTANT("SOL_TCP", pe->p_proto, CONST_CS | CONST_PERSISTENT); } Normally the third parameter can be set to 0. In the original BSD Socket implementation the third parameter (there are 8 different types, here only two) should be IPPROTO_TCP or IPPROTO_UPD (or one of the 6 others ones). These two parameters are though not warpped in PHP as constants and therefore not available. Please use SOL_TCP and SOL_UDP. e.g.: $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); Please be aware of the fact that UDP and TCP can only be used with AF_INET which is: "Adress Family Internet". With UNIX Domain sockets TCP/UDP would make no sense! best regards -Richard-Moh Samar -- http://www.php.net/manual/en/function.socket-create.php http://master.php.net/manage/user-notes.php?action=edit+19032 http://master.php.net/manage/user-notes.php?action=delete+19032 http://master.php.net/manage/user-notes.php?action=reject+19032
