php spark server on production web server

Hi,
I studied your post completely but it had nothing to do with my question. perhaps you didn't read my question carefully.
my question was very simple. I've run 'php spark serve' at the cPanel terminal in a shared host !
Does running 'php spark serve' at the cPanel terminal have a negative effect in the operation of my application ?! if yes, now what action should I take to make up for this mistake?
since the documentation says:
" The built-in development server should only be used on local development machines. It should NEVER be used on a production server."
