Hey, just DONT CLOSE THE BUG IF YOU DON'T EVEN READ IT!
(This is to tony2001@php.net, who closed bug 31118)
here is SIMPLER TEST CASE - no modifications of the array itself - two foreach loops show different contents


Reproduce code:
---------------
  $a = array('key1'=>'value1', 'key2'=>'value2', 'key3'=>'value3');
  foreach($a as $k=>&$v) {
    echo $k . '=' . $v . "\r\n";
  }
  foreach($a as $k=>$v) {
    echo $k . '=' . $v . "\r\n";
  }
// See? No values are modified!!! All explanations to other bugs do not cover this problem

Expected result:
----------------
key1=value1
key2=value2
key3=value3
key1=value1
key2=value2
key3=value3

Actual result:
--------------
key1=value1
key2=value2
key3=value3
key1=value1
key2=value2
key3=value2 <- should be 3
