New Comment:
I don't agree with that change, because if we add such info to count()
we would have to add it to all functions.
If you use an uninitialized var in PHP, you will get a E_NOTICE. This
isn't specific to count().

PHP 4 also gives a warning:
C:\php4>php-cli -r "error_reporting(E_ALL); echo count($a);"
Notice: Undefined variable: a in Command line code on line 1
0

That was not the point Nuno, thebehavior changed regarding
non-initialized values..that can be documented just fine.

It stills return 0.
Try echoing its value with: '<? echo count($a); ?>'
