"Please also note that setting any of the CLI debugging options will not work with remote host debugging, because the script is always launched locally. If you want to debug a CLI script on a remote host, you need to launch it manually from the command line."
Ok, the PHP script is remote, on a homestead VM.
So how do I run, on the command line, the script that sites remotely on the VM, so that I can debug on my host IDE ?
