How to make a scheduler in php, specifically launching scripts at the scheduled time and date?

Question

PHP

Good afternoon, I started to study the yii2 framework, set myself the task of writing a post scheduler in VK, so to speak,
get acquainted with the framework on a specific task, the question arose of how to make the scheduler so that it sends posts at a given date and time, cron seems to me to be of little use for such a task

Answer 1

Any planner. Not necessarily crowns. You can even write it in php. (google "php daemon")

Answer 2

Set the script in CRON to be executed every minute and do what you need in the script at the scheduled time.
