 New Comment:

Thanks for reporting. I verified with 4.2.0-dev & 4.0.6.
This is _VERY_ bad bug...

[root@dev etc]# php
<?php
       $outsidearray = array("key1","key2");
       $insidearray = array("0","1");

           while(list(,$outerval) = each($outsidearray)){
               //$placeholder = $insidearray;
               while(list(,$innerval) = each($insidearray)){
                       print "inloop $innerval for $outerval<br>";
               }
       }
?>

inloop 0 for key1<br>
inloop 1 for key1<br>

[root@dev etc]# php
<?php
       $outsidearray = array("key1","key2");
       $insidearray = array("0","1");

           while(list(,$outerval) = each($outsidearray)){
$placeholder = $insidearray;
               while(list(,$innerval) = each($insidearray)){
                       print "inloop $innerval for $outerval<br>";
               }
       }
?>

inloop 0 for key1<br>
inloop 1 for key1<br>
inloop 0 for key2<br>
inloop 1 for key2<br>

[root@dev etc]# 
[root@dev etc]# php -v
4.2.0-dev

nested while(list=each) produces weird results.
this code

<?php
       $outsidearray = array("key1","key2");
       $insidearray = array("0","1");

           while(list(,$outerval) = each($outsidearray)){
               //$placeholder = $insidearray;
               while(list(,$innerval) = each($insidearray)){
                       print "inloop $innerval for $outerval<br>";
               }
       }
?>

only gets to key1 of the outer loop.
But if you uncomment the $placeholder line,
it works ok.
