New Comment:
That has nothing to do with a foreach. The same effect can be seen
with:
$a = 'foo';
echo $a['bar'];
$a is a string which is essentially an array of characters with
numerical indices. Given that, 'bar' is converted to an integer, so you
end up with $a[0] which does exist, so no warning.

Description:
------------
An array with no associative keys doesn't throw a notice or error when
one is used as an associative keyed array.
Reproduce code:
---------------
<?php
$array = array('foo', 'bar', 'baz');
foreach ($array as $a) {
echo $a['foo'];
}
?>
Expected result:
----------------
Notice: Undefined index
Actual result:
--------------
fbb
