The simplest solution I have is
//Copy works
foreach($array = $object->array as $element)
{
print($element);
}
However, if you want to access the array elements by reference instead
of copy, then you're in trouble.
Even this produces the same error:
$array_ref =& $object->array;

I've just run into this problem, here is my test case
Testcase:
---------
class Language {
private $lang_bits = array();
public function __get($lang_bit) {
global $$lang_bit;
if(!isset($this->lang_bits[$lang_bit])) {
$this->lang_bits[$lang_bit] = $$lang_bit;
}
return $this->lang_bits[$lang_bit];
}
}
$page = array('bla' => 'xyz');
$lang = new Language;
foreach($lang->page as $lang_key => $lang_bit) {
echo $lang_key.' => '.$lang_bit;
}
Expected Results :
------------------
bla => xyz
Actual Results :
----------------
Fatal error: Cannot access undefined property for object with
overloaded property access
Just confirming its presence in 5.0.2 WinXP SP2 Apache 1.3.31

I know the class doesn't have a member called 'cows'. That's what
__get() and __set() is for after all. If I change the code to
$O->cows = array("Betty", "Agnes", "Jeff");
$temp = $O->cows;
foreach($temp as $cow) {
echo "<div>$cow</div>";
}
Now why should it fail just because the property access is through
foreach()?

Your 'Object' object doesn't have a 'cows' member variable. The
"object
with overloaded property access" that the warning is telling you about
doesn't exist is this:
$O->cows
Which 'cows' are you referring to?
