这里记录下 一点 为什么在 LogFirePHPWriter 的构造函数里面 使用 自定义的
# // 注册脚本结束时要运行的方法，将缓存的日志内容写入文件 # ShutdownCallback::getInstance()->add(array($this, '__writeLog')); 而不使用 类的 析构函数 来自动设置写入... 这个原因 在于 异常的出现 , 当出现异常时 完全就抛出异常了 不会再进行 这个操作了.... 所以 使用 自定义的 ShutdownCallback 来保证会被脚本100%执行.... 这些都是 sfw 里面的代码 .... 呵呵... ShutdownCallback 很简单 ... 就一个基本类
<?php
/**
* 对register_shutdown_function 函数栈的扩展
*
*/
final class ShutdownCallback {
private $_stack = NULL;
private function __construct(){
$this->_stack = array();
register_shutdown_function(array($this, 'flush'));
}
/**
* 返回 ShutdownCallback 类的单例对象
*
* @return ShutdownCallback
*/
static function getInstance(){
static $inst = NULL;
if (!$inst)
$inst = new self();
return $inst;
}
/**
* 向框架注册一个脚本结束时要调用的方法
* 此方法用于取代 类的 析构函数,当脚本运行出现异常或者错误时,析构函数并不执行
*
* $callback 类型:
* 1. 字符串 -- str_func_name
* 2. 数组 -- array($class_or_obj,$method)
* @param mixed $callback
* @param array $params
*/
function add($callback,array $params=null){
if (is_callable($callback))
$this->_stack[] = array($callback,$params);
}
function flush(){
while(!empty($this->_stack)){
list($callback,$params) = array_pop($this->_stack);
call_user_func_array($callback,$params);
}
}
}
