isset function work abnormal

[navisoft]

The isset function in the Zephir and the pure PHP return different result.

Zephir:

var test; let test = null; var_dump(isset(test));

var obj; let obj = new Obj; let obj->property = null; var_dump(isset(obj->property));

Output:
bool(true)

Pure PHP:

$test = null; var_dump(isset($test));

$obj = new stdClass; $obj->property = null; var_dump(isset($obj->property));

Output:
bool(false)
