You can print a scalar quantity, even if it is an array element.
However, if the element is itself an array, you can assign the array buy
not print it. If you're getting Array, you have an array, not a scalar.
But I don't see anything in your sample code which would print Array[0],
so I have no idea what you might actually be doing.

Your biggest problem is you are still trying to equate PHP to Perl.
It's a HUGE mistake to do that (no matter what the language). Trying to
look for the differences will only confuse you.
