actually the expected result is Undefined index: b... or to have the variable $php_errormsg defined.

Description:
------------
according to the manual(http://ie1.php.net/manual/en/language.types.array.php):

Note:
Attempting to access an array key which has not been defined is the same as accessing any other undefined variable: an E_NOTICE-level error message will be issued, and the result will be NULL.



Test script:
---------------
        $a ['a'] = null;
        

        $tmp = $a['a']['b']; // nothing
        $tmp = $a['a']['b']['c']; // nothing

// this works (throw an E_NOTICE) fine
$a ['a'] = array();
$tmp = $a['a']['b']; // Undefined index: b
$tmp = $a['a']['b']['c']; // Undefined index: b


Expected result:
----------------
assert(isset($php_errormsg) === true);

Actual result:
--------------
Undefined index: b
