Subject: get_property_ptr
From: sterling@bumblebury.com (Sterling Hughes)

hey,

I'm working on simplexml (sources available in pecl), and I want it to
work in a foreach() loop without requiring the use of a temporary
variable, ie:

books.xml
<books>
 <book>
  <title>The Grapes of Wrath</title>
  <author>John Steinbeck</author>
 </book>
 <book>
  <title>The Pearl</title>
  <author>John Steinbeck</author>
 </book>
</books>

books.php
<?php
$books = simplexml_load_file('books.xml');
$booklist = $books->book; // must assign to a temporary variable
foreach ($booklist as $book) {
    echo "{$book->title}\n";
}
?>

So I'm trying to figure out how to use the get_property_ptr callback. 
I've tried a few things:

1) zend_object_create_proxy.  The docs say I can just return a proxy
object, however, this causes a segfault for me:

return zend_object_create_proxy(object, member TSRMLS_CC);

2) Adding indirection.  I just call property_read, and then return a
pointer to the result of the property_read call.  This also yields a
segfault.

So, any insights on how I might be a smarter boy, and actually get this
thingy to work? :)
