PHP Bug Type: Scripting Engine problem
Bug description: __get called on isset($obj->test[0]) (__isset not tested
before)
Description:
------------
On testing if an array key is available on an overloaded object variable
it doesn't check __isset before calling __get to get the variable for
checking the array key.
Reproduce code:
---------------
class MyClass
{
public function __isset($varname)
{
echo 'isset' . PHP_EOL;
return false;
}
public function __get($varname)
{
trigger_error('Key "' . $varname . '" does not exist',
E_USER_NOTICE);
}
}
$obj = new MyClass();
var_dump( isset($obj->test[0]) );
Expected result:
----------------
isset
bool(false)
Actual result:
--------------
PHP Notice: Key "test" does not exist in /tmp/test.php on line 14
Notice: Key "test" does not exist in /tmp/test.php on line 14
bool(false)
