What actually matters is what you do with it afterward.  If we assume 
you are iterating the array, will you get undesirable affects from 
looping over a single empty value?  If so, why?

Let me ask this: if you had a string like this: "a|b||c", then explode 
would give 4 values and one of them would be empty.  If you need a 
special handler for that then you've probably coded it already and your 
code should handle PHP's behavior just fine.  If you do not need a 
special handler then your code will probably still run just fine.

Is there some reason your downstream code will break on an array of one 
empty string?
