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); ?>'

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
