Unexpected behaviour when running foreach across an array of objects in PHP

foreach-wierdness.php

<pre>
<?php

/*
after using foreach to iterate /by reference/ across an array containing objects,
then on the second foreach of the same array, 
the final member of the array gets overwritten by the previous
and c=b

if we don't iterate by reference on the first pass, then it doesn't happen
and c=c at the end

is this right?
*/

  $array = array(
    'a' => new stdClass(),
    'b' => new stdClass(),
    'c' => new stdClass(),
  );
  $array['a']->name = 'a';
  $array['b']->name = 'b';
  $array['c']->name = 'c';
  // by reference
  foreach ($array as $k => &$value) {
    print($k . ' is '. $value->name . "\n");
  }
  // no reference this time, but last member gets clobbered
  foreach ($array as $k => $value) {
    print($k . ' is '. $value->name . "\n");
  }

/*
a is a
b is b
c is c
a is a
b is b
c is b <---------------------
*/

// ok, let's try that again

  // reset the array
  $array = array(
    'a' => new stdClass(),
    'b' => new stdClass(),
    'c' => new stdClass(),
  );
  // some properties
  $array['a']->name = 'a';
  $array['b']->name = 'b';
  $array['c']->name = 'c';
  // no reference
  foreach ($array as $k => $value) {
    print($k . ' is '. $value->name . "\n");
  }
  // again, no reference; last member is OK
  foreach ($array as $k => $value) {
    print($k . ' is '. $value->name . "\n");
  }

/*
a is a
b is b
c is c
a is a
b is b
c is c <---------------------
*/

Yeah, PHP has crappy variable scoping. OTOH, they'd probably make lexical scoping suck too.
