No, actually, if it's a string, it's a single item --- thus, 1.
The documentation should probably reflect that as well. It wasn't
always this way before, though --- in older version of PHP5 it
returned 0, and in all versions of PHP4 it did as well.
Also, keep in mind that a blank string still constitutes a string
and will return 1, but null or nonexistent variables will still return
0.
