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

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.
