PHP Bug Type: *General Issues
Bug description: isset and empty returns wrong value
Description:
------------
If you try to check the existence of a property on an array, suprisingly
you wont get any error or notice, but you will get the results as you were
checking with the correct type.
Reproduce code:
---------------
<?php
$a = array('foo' => 'bar');
echo "<pre>";var_dump(isset($a->foo));echo "</pre>";
echo "<pre>";var_dump(isset($a->asd));echo "</pre>";
echo "<pre>";var_dump(empty($a->foo));echo "</pre>";
echo "<pre>";var_dump(empty($a->asd));echo "</pre>";
echo "<pre>";var_dump(@$a->foo);echo "</pre>";
Expected result:
----------------
Fatal error: Cannot use array as object in ...
OR
bool(false)
bool(false)
bool(true)
bool(true)
NULL
Actual result:
--------------
bool(true)
bool(false)
bool(false)
bool(true)
NULL
