How to update a web page written in PHP on a schedule?

Question

CodeIgniter

CodeIgniter implements the function of sending mail. When a page is updated, for example info.dom.ru/reports/mail , a select goes to the database and messages are sent.
How can I make the page update automatically according to the schedule and is it possible to implement this at all?
Thank you.

Answer 1

Through any scheduler, for example, cron.
You can directly through the php interpreter:
/usr/local/php5/bin/php /path/script.php
If you need to go through mod_rewrite, you can use wget, for example:
/usr/bin/wget -O /dev/null -q info. dom.ru/reports/mail

Answer 2

<script>
window.setInterval(function() {
    window.location.reload(true)
}, 3*60*1000)
</script>

Answer 3

cron
