            ByteArrayOutputStream ostream = new ByteArrayOutputStream();
            ObjectOutputStream op = new ObjectOutputStream(ostream);
            op.writeObject(o);
            op.flush();
            ostream.close();
            return Base64.encode(ostream.toByteArray());   请问在PHP中如何实现Base64 编码

base64_decode(串)为什么不查手册呢?

上面是解码
编码是 base64_encode(object)
