model 的调用
1、获取model对象
获取本app 的model
$model = $this->app->model('$model');
获取其他app的model
$model = app::get('b2c')->model($model);;
更通用的方法kernel::single()
$model = kernel::single('b2c_mdl_$model')
2、在model中获取数据库操作对象
通过调用基类成员变量$db
$result = $this->db->select($sql);
通过kernel::database()直接获取数据库操作对象
$result = kernel::database()->select($sql);
ECOS 中实例化类 的方法
1、app::get('$app')->model('$model');
app::get('$app')->render();
主要用来调用model,base_render类
2、通用方法kernel::single('$class');
主要用来调用lib中的类

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.
