Bug description: unset in foreach breaks recrusion
Description:
------------
Made a simple recrusion function, sorting id by parentid, unsetting sorted
values to shorten time of next recrusions. Unsetting inside foreach with
deep arrays does work(!), but with simple array unset somehow stops the
recrusion (first cicle will never finish its loop, the last loop will be
made by latest child).
Tested with PHP 5.2.6 on Debian-40r3-amd64 and Windows Vista 32
Reproduce code:
---------------
<?php
function recrusion($array, $return, $pid=0, $level=0){
foreach($array as $id=>$parent){
if( $parent===$pid ){
$return[$id]= $level;
unset($array[$id]); /* remove this to get correct
results */
recrusion(&$array, &$return, $id, $level+1);
}
}
}
$return= array();
$array= array(1=>0,2=>1,3=>2,4=>3,5=>2,6=>2,7=>6,8=>6,9=>0,10=>0);
recrusion($array, &$return);
var_dump( $return );
?>
Expected result:
----------------
array(10) { [1]=> int(0) [2]=> int(1) [3]=> int(2) [4]=> int(3) [5]=>
int(2) [6]=> int(2) [7]=> int(3) [8]=> int(3) [9]=> int(0) [10]=> int(0) }
Actual result:
--------------
array(6) { [1]=> int(0) [2]=> int(1) [3]=> int(2) [4]=> int(3) [9]=>
int(0) [10]=> int(0) }
