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( * key=>value, * ); * * 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。 * </span><span>*/</span> <span>return</span> <span>array</span><span>( </span>'2013-12-25 19:49'=>'123.php', '2013-12-* 18:00'=>'456.php', '1 08:00'=>'6546.php', '*-12-25 19:49'=><span>array</span>('444.php','456.php'<span>) );</span>
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。
<span>php </span><span>/*</span><span>* * cron任务统一执行的文件,没有超时 </span><span>*/</span> <span>header</span>('Content-Type:text/html; charset=utf-8'<span>); </span><span>set_time_limit</span>(0<span>); </span><span>define</span>('APP_ROOT', <span>dirname</span>(<span>__FILE__</span><span>)); </span><span>define</span>('AHA_ROOT', <span>dirname</span><span>(APP_ROOT)); </span><span>define</span>('CORE_ROOT', AHA_ROOT .

三、众多要执行的定时文件:
这个是真正要执行的代码:包括采集,数据整理与分析。。。。,文件路径写到配置文件的value中去。同一时间执行的文件,记得一维数组模式。
