Pending posting to PHP?

I must say that the desire to make some services ex. posting no. Purely for yourself.

How do you make PHP a delayed posting? Here is Crowns, it is called, for example, once per minute. That's how it is called - and so fast.
How to make a posting on schedule, but without the Crown (or with him, but not to produce a cron task for every desired date)? Here in VK the delayed posting. I went in, wrote that it is necessary, choose a date and time. Everything on the specified time something is uploaded.
Maybe it's all in PHP?

Solution
In php like any other language is possible almost everything. Your task is certainly.
Solved simply enough. You keep a list of what is necessary to post and time of post(in database, in file, does not matter). And the cron once a minute a script is run which checks for tasks. If the time has come, then post and delete the task if no task then just falls asleep again.
Thank you, I had originally planned. Just thought there any extra libraries for this? - Emmet.Stoltenberg commented on July 8th 19 at 11:28
there are libraries. But why for such a simple task to haul even third-party libraries? - Donny71 commented on July 8th 19 at 11:31
: just if the day is planned a large number of calls to the task, I thought that libraries will be a little faster. And can you please name the libraries to be called? - Emmet.Stoltenberg commented on July 8th 19 at 11:34

But if lots of users? Do I need for this task to use beanstalkd, rabbitmq, gearman or something? - winfield.Kassul commented on July 8th 19 at 11:40

You can't kill PHP script and spin in a loop until the desired time. If it is to answer your question.
If solve your problem, then - cron. Didn't you just read what is CZK, apparently.
Sorry, I added the answer. Originally not formulated. - Emmet.Stoltenberg commented on July 8th 19 at 11:30

1. Doing an infinite loop in a PHP application and run in daemon mode.
2. Interview task pool and "fall asleep" on time to the next task.
3. Wake up - do.
4. GOTO 2
