我们可以通过PHP脚本配置cron作业的时间间隔吗? [英] Can we configure cron job's time interval through PHP script?

问题描述

我们是否可以通过PHP脚本配置cron作业的时间间隔，以使该时间间隔不应该手动设置，而是通过PHP脚本设置，而不管是数据库时间间隔还是固定时间间隔(而是从PHP代码内部).
预先感谢

Can we configure cron job's time interval through PHP script, so that the time interval should not be set manually, but through a PHP script, whether it takes time interval from Database or fixed (but from within the PHP code).
Thanks in advance

推荐答案

我认为让您的应用程序控制事件的频率而不是cronjob更好.让cronjob每分钟运行您的应用程序的特定操作.例如，该操作然后检查名为cronjobs的数据库表，并运行通过频率编号或时间戳标记为正在运行的作业.

I think it is much better to let your application control the frequency of events instead of the cronjob. Let the cronjob run a certain action of your application every minute. The action then for example checks a database table named cronjobs and runs the jobs marked for running by either a frequency number or a timestamp.

如果您这样做，则可以从任何地方以编程方式添加新作业，例如通过cronjob界面. 该解决方案易于维护，测试和记录.

If you do it like this, you can add new jobs programmatically from everywhere, e.g. via an cronjob interface. The solution is easier to maintain, to test and to document.
