count($var) can return 0 if $var is not set and 1 if $var is not an array. 

In my view these overlap with proper return values - I can have an empty array and I can have an array with only 1 element. Actually, I often do.

Please make count($var) return -1 and -2 in these cases so I can reliably determine what's the situation with $var.

you should use is_array() for argument type checking
*before* calling count() or sizeof()
