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。

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
