php实现的thrift socket server
php-thrift-server源码
代码直接从apache的thrift项目clone过来,托管在github上:
http://github.com/volca/thrift
新增或改动的代码如下:
lib/php/
`-- src
|-- server
| |-- TNonblockingServer.php
| `-- TServer.php
`-- transport
|-- TNonblockingServerSocket.php
|-- TNonblockingSocket.php
|-- TServerSocket.php
|-- TServerTransport.php
test/php
|-- TestClient.php
|-- TestNonblockingServer.php
使用示例
获取thrift的源码,并编译出thrift工具,编译过程请搜索
git clone git://github.com/volca/thrift.git安装php,以及apc, libevent扩展:
pecl install apc#需要先libevent-devel之类的包包pecl install libevent运行php的socket服务器,我直接从thrift的test代码中修改了一个独立运行的php server,见thrift/test/php/TestNonblockingServer.php,这里也包含一个测试业务代码的实现。
cd thrift/test/php#用thrift命令行工具生成php的测试类库make#启动thrift服务,会监听本机的9090端口php TestNonblockingServer.php客户端的代码也一并提供,对各种数据类型比如int, float, string, list等等进行测试。

thrift是什么?
thrift流传的似乎不是太广泛,而且有被别的技术替代的趋势,所以下面还是引用一下别的文章的介绍:
Thrift由一个软件库和一系列的代码生成工具组成,由 Facebook开发。目的是为了加快软件开发和实现高效和可扩展的后台服务。主要目标是不同程序开语言之间实现高效和可靠的通信,这需要将不同语言之间抽象出一个通用层,然后由不同语言来实现这个通用层。在这里要特别指出的是,Thrift允许开发人员定义数据类型和服务接口(定义在一个中性语言文件里),并通过这个文件生成构建RPC客户端和服务端所需的代码。
简单分析其机理,Thrift就是实现C/S模式,通过代码生成工具将接口定义文件生成服务器端和客户端代码(可以为不同语言),从而实现服务端和客户端跨语言的支持。
Thrift可以分为传输层和协议层:
传输层定义了数据的传输方式,可以为TCP/IP传输,内存共享或者文件共享等形式;
协议层定义了数据的传输格式,可以为二进制流或者XML等形式。
当服务器端使用socket协议时,可以用simple|thread-pool|threaded|nonblocking等方式运行,从而获得更好的性能。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
