Hello, I would like to know if it’s possible to host my PHP script here, like is it possible to run my PHP script here and it would keep running 24/7? and if I upload any files here, would it stay here and get saved?
Also, is it possible to change the PHP version to 7.3?
If you want to keep a server up and running at all times, I'd recommend UptimeRobot. All you need to do is create an account and set up a monitor to ping the server every 5-ish minutes.
Uploaded files should persist even after closing.
Changing the PHP version is something only the Repl team can really do. I'd suggest you post to the Feedback page about it.
btw, when I click on the button that opens a tab to the web server of my script, (the script just has an echo) it says "This site can’t be reached" and that it took too long to respond, why is that?
