Erlang二进制包

Question

我对Erlang非常陌生，我正在转换一些PHP的东西，我无法弄清楚这一点。这里是PHP函数：

public function raw_send($string1, $string2 = NULL, $type = SERVERDATA_EXECCOMMAND) { 
$data = pack('VV', $this->get_request_id(), $type) . $string1 . chr(0) . $string2 . chr(0); // build data 
$packet = pack('V', strlen($data)) . $data; 
fwrite($this->fp, $packet, strlen($packet)); 
} 

这是我的尝试：

raw_send(Sock, String1, String2, Type) -> 
    RequestId = random:uniform(10), 
    PacketData = list_to_binary([<<RequestId, Type>>, String1, 0, String2, 0]), 
    DataLength = byte_size(PacketData), 
    Packet = list_to_binary([<<DataLength>>, PacketData]), 
    ok = gen_tcp:send(Sock, Packet). 

我使用CRC32比较的东西试过，包（ “VV”，1，3）在PHP应该= < < 1/unsigned-little，3/unsigned-little >>，no？

而且，我想要做的规格：http://developer.valvesoftware.com/wiki/Source_RCON_Protocol

HALP！

谢谢

明白了，没有使用32位整数！ （感谢ndim @ freenode）

raw_send(Sock, String1, String2, Type) -> 
    RequestId = random:uniform(10), 
    String1Bin = list_to_binary(String1), 
    String2Bin = list_to_binary(String2), 
    PacketData = <<RequestId:32/little, Type:32/little, String1Bin/binary, 0, String2Bin/binary, 0>>, 
    DataLength = byte_size(PacketData), 
    Packet = <<DataLength:32/little, PacketData/binary>>, 
    ok = gen_tcp:send(Sock, Packet). 

希望能帮助别人！
