Description:
------------
In function.count I see:
"count() may return 0 for a variable that isn't set", but is not true
with PHP5 with E_NOTICE turned on
I have tried to patch it:
--- count.xml 2004-11-03 10:30:02.000000000 +0300
+++ count_new.xml 2005-01-01 19:45:24.000000000 +0300

isn't set, but it may also return 0 for a variable that has
been initialized with an empty array. Use
<function>isset</function> to test if a variable is set.
+ Since PHP 5.0.0, <function>count</function> generates warning of
level
+ <link linkend="errorfunc.constants">E_NOTICE</link> in case of
taking non-initialized variable as parameter.
