A little confusing thing when try to get something from a string using multi dim offset

Hi guys, I posted a topic on php.general when I had some problem on getting something from a string using multi dim offset here: http://news.php.net/php.general/323297. Here is a TL;Summary version: $data = 'here\'s some data'; In PHP 5.5 it will be: var_dump(isset($data['string'])); === false var_dump(isset($data['string'][0])); === true Other bright people in php.general already explained how it happens, and I get it. But before get use to it, I think I should post this to do some ... complain ... if you will. It's confusing, I have to say. Because the isset($data['check']) is false, so the isset($data['check'][0]) should be false too, theoretically, but it's not. Is any chance to get var_dump(isset($data['string'])); === false var_dump(isset($data['string'][0])); === false <-- ? Because it will be more intuitively right and make PHP more user friendly. Thank you.
