Cron 在时隙之间每 5 秒运行一次 PHP 脚本

Question

How to run the PHP Script automatically every 5 seconds between the time slots 13:00:00 to 14:00:00 and 16:00:00 to 17:00:00 everyday?

PHP Script:

<?php
$datetime = date("l jS \of F Y h:i:s A"); 
$apiToken = "1825671537:AAEYexjklpoiyUdEeG8Ml";
$telegram_chatid = '-10012345607';
$message = urlencode($datetime);
                
$telegram_call = file_get_contents("https://api.telegram.org/bot$apiToken/sendMessage?chat_id=$telegram_chatid&parse_mode=markdown&text=$message");
exit();
?>

Answer 1

Use a for loop to run the process 12 times with a 5-second sleep between calls. Use cron to run this every minute.

* 13  * * *  for i in {1..12}; do (php telegram.php &); sleep 5; done;
* 16  * * *  for i in {1..12}; do (php telegram.php &); sleep 5; done;

The program is detached using & , so the sleep happens directly and not after the script is finished, ensuring it's run every 5 seconds.

Well you can't do it with the cron job but you can use the cron job as an initiator.

This could be a way to solve this issue. you can run a cron job everyday at 13:00 o'clock.

Your script on the other hand should have a loop which sleeps 5 second and goes again through the loop. Once you reach 17:00 o'clock it will stop the loop and exit.

And there should be another check in the loop, which checks whether you are between the given time eg 13:00-14:00 or 16:00-17:00, if so it will run your script and sleep 5 seconds, if not it will just run the the loop

Another way would be to run a cron job every hour. And in your script you have to check it the hour is the one you want to start doing something. if so, you just do it like the above loop.
