# Spawn a Bash shell with the app environment loaded

#
# examples:
# ynh_spawn_app_shell "foobar" <<< 'echo "$USER"'

# from the app's service configuration file (defaults to $app.service, overridable by the packager with `service` setting).
# If the app relies on a specific PHP version, then `php` will be aliased that version. The PHP command will also be appended with the `phpflags` settings.
