As for the array behavior, it's trickier, we need to think about it. Using an object that can cast itself to an array and implements the 'get' method (to fetch its value) may be the right answer.

The problem is one of simplicity ;)
I ran into the same problem a couple days ago. In the two examples, an array of element 'child' is expected. That array may be one or more elements. SimpleXML turns multiple children of the same element name into array's, but a single child is not. I'm not sure what the right answere is for it though, other than conditionaly checking for a single child.
There's a part of me that thinks that children should be accessed via a function, but then you start getting dom-like:
$root->childNodes()[0]
and it always works. It also prevents problems with something like:
<root child="test"> <child>abcd</child> </root>

The following script
<?php $root = simplexml_load_string(' <root> <child /> </root> ');
foreach ($root->child as $child) { var_dump($child); } ?>
does not print anything while
<?php $root = simplexml_load_string(' <root> <child /> <child /> </root> ');
foreach ($root->child as $child) { var_dump($child); } ?>
correctly prints
object(simplexml_element)#2 (0) { } object(simplexml_element)#3 (0) { }
