Prevent long running PHP script from closing

Question

I'm running a php script via cli, so it can run in background. This script is suposed run 24/7. How can I prevent it from shutting down (on errors, warnings, etc) and restart immediatly if it happens?

Thanks in advance!

Answer 1

You could use a shell script to call php in an infinite loop, and run the shell script in the background. For example (a bit simplistic) a script like this, say "runloop.sh":

#!/bin/bash
# Run php script in a loop
while true; do
  php phpscript.php
done;

...and then run that script in the background, or from init. From the command prompt:

$ ./runloop.sh &

...to run the script in the background. It should run forever, unless you kill it somehow.

I should add that you'll need to make the shell script executable:

$ chmod +x runloop.sh
