PHP socket实现 writeInt 和 writeLong 和 writeUTF 以及和Java端对接

function writeInt($socket, $i)
{
$data = pack('N', $i);
socket_write($socket, $data);
}

function writeLong($socket, $i)
{
$data = pack('J', $i);
socket_write($socket, $data);
}

function writeShort($socket, $i)
{
$data = pack('n', $i);
socket_write($socket, $data);
}

function writeUTF($socket, $i)
{
writeShort($socket,strlen($i));
socket_write($socket,$i);
}

DataInputStream stream = new DataInputStream(new BufferedInputStream(socket.getInputStream()));

int i=  stream.readInt();

long l =  stream.readLong();

String s = stream.readUTF();

socket.close();
