Add checks for missing or empty arrays

Thanks for submitting the issue and patch. I'll take a look.

I've attached a newer version of the patch that uses PHP's Null Coalescing Operator (https://www.php.net/manual/en/migration70.new-features.php#migration70.n...) to make these changes more simple.

Please let me know if this patch still fixes these issues for you.

Thanks for the quick response! I applied your patch and everything still works as expected.

#5 works for me
