The manual explains what the function does - you may want to check it out cos
it does the same for all the other functions too.
"Returns the number of elements in var. If var is not an array or an object
with implemented Countable interface, 1 will be returned. There is one
exception, if var is NULL, 0 will be returned."
IOW, if you pass it a variable, that has one element, so it returns 1. An array
may have 0 to many elements, and null, logically, has none. Rocket science this
