PHP钩子与简单分发方式实例分析

//简单的钩子实现例子
class tool{
  public static function main($class, $fun, $data = ''){
    //前置公共操作
    $con = new $class;
    $con->$fun($data);
    //后置公共操作
  }
}
class a{
  function b($data){
    echo '我是方法b';
  }
}
class c{
  function d($data){
    echo '我是方法d';
  }
}
//钩子调用
tool::main('a','b','222');
