Exactly. That's why the recommended setting for "display_errors" in
production environments is "Off":

Actually, you don't get an error, you get a _notice_. PHP tells you that
you are trying to read a value from an array that does not exist. That's
a very useful piece of info for you as developer. Notices help you to
identify potential bugs.

You're free to configure your environment so it doesn't trigger any sort
of error, warning or notice[1], but it won't make your coding task
easier. On the contrary, it'll make it harder in the long term. Trust me :)
