Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

RTFM: 

http://php.net/count 

"There is one exception, if var  is NULL, 0 will be returned."

http://php.net/array

"Converting NULL to an array results in an empty array."

Description:
------------
Example A "compiles" and B does not (E_NOTICE).

Invoking an array index on NULL *probably* warrants my attention more
than doing so on an array.

It has cost me countless hours, for one.

Reproduce code:
---------------
// A
$foo = null;
count( $foo['bar'] );

// B
$foo = array();
count( $foo['bar'] );


Expected result:
----------------
2 E_NOTICE errors

Actual result:
--------------
1 E_NOTICE error
