推荐答案

无法延迟执行当前脚本中的部分代码。这也没有多大意义，因为PHP脚本的处理完全在服务器端进行，你只会延迟脚本的整体执行。有 sleep（）但这只会暂停一段时间。

There is no way to delay execution of part of the code of in the current script. It wouldn't make much sense, either, as the processing of a PHP script takes place entirely on server side and you would just delay the overall execution of the script. There is sleep() but that will simply halt the process for a certain time.

你当然可以，安排PHP脚本使用cron作业等在特定时间运行。

You can, of course, schedule a PHP script to run at a specific time using cron jobs and the like.
