Description:
------------
I tried to access an array key by string value.
But the variable I accessed was no array, but a string.

As stated in the manual you can access single chars by numeric array keys, which 
makes perfect sense.
But if I try to use a string it is treated as 0 (zero).

Too much type jugglin'?

Test script:
---------------
<?php 
  $link = "foo";
  echo $link['bar'];
?>

Expected result:
----------------
PHP NOTICE - $link['bar'] is not defined.

Actual result:
--------------
