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

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.
