Awesome, here's a possible compat function:
function compare_diff516($a, $b)
{
if (is_object($a) || is_object($b))
return $a == $b;
return strcmp($a, $b);
}
function array_diff516($a, $b)
{
return array_udiff($a, $b, 'compare_diff516');
}

Use array_udiff with user supplied callback, the old behaviuor looks
wrong to me.
array_diff does compare with (string) $elem1 === (string) $elem2 and as
stdclass does not implement __toString() it emits a correct fatal error.

Description:
------------
Upgrading from PHP 5.1.6-1 (Debian) to 5.2.1 (Ubuntu) a regression has
appeared in array_diff(). Comparisons now fail when an array member is
a stdClass object.
Also reproduced with 5.2.4RC1-dev.
Reproduce code:
---------------
<?php
$dogs = array();
$poodle = new stdClass;
$poodle->collar = 'red';
array_push($dogs, $poodle);
array_push($dogs, 'terrier');
array_push($dogs, 'dalmation');
$cat = array('persian' => array(1, 2, 3));
var_dump(array_diff($dogs, $cat));
?>
Expected result:
----------------
array(3) {
[0]=>
object(stdClass)#1 (1) {
["collar"]=>
string(3) "red"
}
[1]=>
string(7) "terrier"
[2]=>
string(9) "dalmation"
}
Actual result:
--------------
Catchable fatal error: Object of class stdClass could not be converted
to string in /miru/home/steve-o/- on line 11
