$string['foo'] will raise a notice as of PHP 5.4, so I'd say this is fixed, so
I'm closing here.

See also:
* Bug #48560 - E_STRICT does not report error if booleans or ints are used as
arrays
* Request #37676 - using Array access operator [] on boolean variable does not
show Notice
Dupe it to the latter?

FWIW: $string['foo'] is equivalent to $string[0] and in your case it won't
trigger any notice indeed because the offset 0 is defined.

Description:
------------
It seems strange that when the strictest level or error reporting is enabled an
E_NOTICE is thrown when attempting to access a non-existent key of an array,
but nothing is thrown when attempting to access a non-existent key of a bool,
or a string, or it appears any other variable type. An E_NOTICE will also be
thrown if attempting to access a non-existent numerical key in a string, but
not if attempting to access a non-existent non-numerical key.
If an E_NOTICE is displayed under one circumstance for an index not existing it
seems that it should be displayed under all circumstances when an index doesn't
exist.
Reproduce code:
---------------
error_reporting(E_ALL | E_STRICT);
$dummyArray = array();
// this will throw an E_NOTICE
$error = $dummyArray['doesNotExist'];
$dummyArray = true;
// this will not throw an E_NOTICE
$noError = $dummyArray['doesNotExist'];
$dummyArray = 'string';
// this will not throw an E_NOTICE
$noError = $dummyArray['doesNotExist'];
// but this will throw an E_NOTICE
$error = $dummaryArray['100'];
Expected result:
----------------
Notice: Undefined index: doesNotExist
Notice: Undefined index: doesNotExist
Notice: Undefined index: doesNotExist
Notice: Uninitialized string offset: 100
Actual result:
--------------
Notice: Undefined index: doesNotExist
< nothing when attempting to access a non-existent key of a bool >
< nothing when attempting to access a non-existent key of a string >
Notice: Uninitialized string offset: 100
