Hello again,

Sure, I'm expecting an array, but I'm expecting it to be empty like the
string it originated from.

Let's say I get a field value from a database that is usually formatted like
"1|2" but could also be "1" or "". If I leave it as a string, I can easily
tell if it has data in it with a simple conditional. But if I explode the
string to work with its individual elements, I can't easily tell anymore;
count() returns 1 and empty() returns false even if the original value was
"".

I guess I could test for (implode(",", $array)), which returns false if the
array consists only of one empty element. Or I could write a new function.
Is there a better way?

Since this comes up so often for me, it seemed like something that should be
built in, but I'll settle for a more elegant workaround than the one I'm
using now.

Cheers,
-Arlo
