The manual says that count "returns 1 if the variable is not an array." This can produce inaccurate results if the variable is an array, but has only one element.

Temporary Solution:
Don't use count(). Instead use is_array(), isset(), and sizeof().

Solution:
Set integer returned by count() to (-1) when the tested variable is not an array.

I don't see how 1 is inaccurate.  Think of a variable as a 1-element array.  count() was never designed to distinguish between arrays and variables.  It was simply designed to tell you how many elements something contains.  Having it return -1 would be counter-intuitive.
