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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50255&edit=1
