明天前的工作安排 [英] cron job minute before tomorrow

问题描述

我即将通过curl触发对PHP文件的调用。我正在考虑让脚本每隔 23:59:59 或明天开始前一分钟执行一次。有什么最好的办法吗？仍然对cron设置感到困惑。

I am about to trigger a call to a PHP file via curl in a schedule basis. I am thinking of having the script to be executed every 23:59:59 or simply a minute before the day turns tomorrow. Any best approach for this? Quite confused still on the cron settings.

我需要确保第二天前一秒才跑步。

I need to ensure that I run at exactly a second before the next day.

推荐答案

要每天在23:59:00执行脚本，请使用以下命令：

To Execute a script every day at 23:59:00, use the following:

59 23 * * * root /path_to_file_from_root

不能使用Cron ，但这应该对您有用。

Seconds cannot be defined using Cron, but this should do for you.

要在23:59:59执行脚本，请使用PHP sleep（ ）函数将脚本执行延迟59秒。不过我建议58秒，以确保脚本不会延迟到午夜之后。

To execute the script at 23:59:59, use the PHP sleep() function to delay the execution of the script by 59 seconds. I would advise 58 seconds though, just to make sure the script doesn't delay until after midnight.

这是非常基本的操作，您可以将其做一点更复杂的运行测试，以通过检索时间并适当延迟来确保脚本始终在23:59:59运行。

<?php

    // Any work that the script can do without altering the database, do here

    // Delay the script by 58 seconds
    sleep(58);

    // Carry on with the rest of the script here, database updates etc

?>
