实际项目中会在php代码层面判断运行环境拥有哪个拓展就调用哪个
开发环境大多是WIN,就用memcache
生成环境大多Linux,就用memcached
<code> if (extension_loaded('memcached')) { $this->cache = new \Memcached; }else if(extension_loaded ('memcache')) $this->cache = new \Memcache; else{ $this->active = false; Log::error('Cache not support!'); return false; } </code>

Memcached 是一个受欢迎的选择,它能配合许多语言使用,包括 PHP。
然而,从一个 PHP 脚本中访问一个 Memcached 服务器,你有两个不同且命名很愚蠢的客户端库选择项:Memcache 和 Memcached。 它们是两个名字几乎相同的不同库,两者都可用于访问一个 Memcached 实例。
事实证明,Memcached 库对于 Memcached 协议的实现最好,包含了一些 Mmecache 库没有的有用的特性, 并且看起来 Memcached 库的开发也最为活跃。

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.
