Hello,

I am still not sure what you are trying to solve here.

&network2bin() has two possible return values:

1) An array with two values

Or

2) Undefined

You are now checking if you have an array with any length but two, but this won’t work for undefined. That should at least print a warning that you are trying to determine the length of an undefined array.

So why is this change needed?
