PHP Code – How to create a Live Demo for free on 000webhost.com (outdated)
People often ask me, how i created the live demo at https://phpfm-demo.000webhostapp.com.
It resets automatically every hour, and shows a timer for the next reset.
Here i share the code, so if you have a project on GitHub and want to create a live demo, you can use it as base.
000webhostapp.com is a free webhosting service, and all you have to do is leave their banner on your demo.
demo-reset.php
This is the main script, it runs on my server crontab every hour.
<?php
// Run on CRON every hour
// 0 * * * * www-data wget -q --spider http://[URL TO DEMO-RESET] >/dev/null 2>&1
