继续转 [转]php版本的cron定时任务执行器-php手册-php.cn

由于服务器crontab只能精确到分钟，那程序的起点也是分钟。一共包括但部分：一、配置文件：配置文件是用来返回要执行的定时任务文件，注意一下*的使用就行了，有两个模式，就是 Y-m-d H:i ：年月日时分N H:i ：星期(1 - 7|周一 - 周日) 时分配置文

由于服务器crontab只能精确到分钟，那程序的起点也是分钟。

一共包括但部分：

一、配置文件：

配置文件是用来返回要执行的定时任务文件，注意一下*的使用就行了，有两个模式，就是

Y-m-d H:i        ：年 月 日 时 分
N H:i            ：星期(1 - 7|周一 - 周日) 时 分

配置文件：croning.php

<span>/*</span><span>*
 * 任务管理器配置文件
 * 
 * Y-m-d H:i        ：年 月 日 时 分
 * N H:i            ：星期(1 - 7|周一 - 周日) 时 分
 * 
 * 2013-12-25 19:49 : 固定时间，只执行一次
 * *-12-25 20:00    : 每年的某月某日 某小时某分
 * 2013-12-25 *:49  : 某天的每个小时的49分都执行一次
 * *-*-* 20:00      : 每天晚上8点0分执行
 * *-*-* *:*        ：每分钟都在执行
 * 2 20:01          ：每周二的20:01时间都执行一次
 * 
 * * 号表示当前位置的任何时间。以此类推....

 * 格式：
 * array(

 * 
 * 说明：
 * key是定义的执行时间，value是执行的文件，可以是数组或者字符串，当同一时间有多个任务执行时，为了避免key的覆盖请用一维数组模式。

二、服务器cronjob主要执行的php文件：

主要处理与分析哪些文件是当时可以执行的。以及写入执行记录文件。
