Using reset on an array of objects seems to alter the array counters of the object's arrays, even though foreach is not dealing with that array.  Then, as foreach is supposed to, it doesnt reset them.

Example:

class child{
  var $items = array("A1", "A2", "A3");
}
$arr=array(new child, new child, new child);
print "step1<br>";
print sizeof($arr)."<br>";
foreach($arr as $v)
  print $v->items[0]."<br>";  // Three A1 printed
print "<hr>step2<br>";
print sizeof($arr)."<br>";
foreach($arr as $v)
  print $v[1]."<br>";  // No A1 printed
