Bug description: array pointer is different from other versions
Description:
------------
I know that the array pointer doing...
if passing arrays to functions, the pointer of the argument(within the
function) is set to First.
and after the foreach, the pointer is set to First;
But, some version of PHP (like 5.2.6 and 5.2.7-dev) array pointer is
different from other version.
Also, I ever seen it within one of early version of 5.2.6.
test result...
expected result: 5.0.4(FC 4) , 5.1.6(centos 5)
actual result: 5.2.6(centos 4.6) , 5.2.7-dev(centos 4.6)
Reproduce code:
---------------
<?
echo "PHP VER. ".phpversion()."<br><br>";
$a =
array('aa'=>'aa','bb'=>'bb','cc'=>'cc');
$aa = array('a'=>$a,'b'=>$a,'c'=>$a);
function testLoop($datas) {
while (is_array($datas) && list($dk,$data) = each($datas)){
echo $dk ."<br>";
}
}
//next ($aa);
foreach ($aa as $ak=>$av) unset ($aa[$ak]['bb']);
list($k,$v) = each($aa);
echo "$k , $v <br>";
echo "testLoop : unexpected result<br>";
testLoop($aa);
echo "<br>rest & testLoop : expected result<br>";
reset($aa);
testLoop($aa);
?>
