Question

I never used system commands so I would need a little help running a php background process:

1. Can I run an exec() command on a shared server environment?
2. Is it possible not to wait for it to finish in the file I am running it from?
3. Can I use parameters to pass to this file?

Answer 1

1. It depends on the server configuration.
2. Maybe if you use screen.
3. You can use parameters as you would run the command from command line.
