Reproduce code: --------------- $foo = 'foo'; var_dump($foo); echo '<br />'; var_dump(isset($foo['bar'])); Expected result: ---------------- string(3) "foo" bool(false) Actual result: -------------- string(3) "foo" bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=37727&edit=1
