Bug description:Insufficient+Inconsistent error reporting
Description:
------------
If you try to access an undefined index on an array, you will get an error.
But if you try the same on bool(false) PHP will silently accept it and
ignores the error.
Please note that this is especially dangerous on database results, where
you get false instead of an array when there is no result.
If you try the same on a valid array with an invalid index you will get a
E_NOTICE.
So trying to use the array operator on a non-array should at least raise an
E_STRICT error, indicating that there is a problem, instead of silently
continuing to use the wrong result for further calculations.
Test script:
---------------
$array1 = false;
$array2 = array('a'=>3);
echo 5+3*$array1['a']; // output: 5
var_dump($array1['b']); // output: NULL
var_dump($array2['b']); // output: <b>Notice</b>: Undefined index: b
