Bug description: strange behaviour on saving arrays with moved cursors in
Session
Description:
------------
you define an array
step through ONLY SOME elements using list-each structure
stepping through you perform some changes on data
finishing the while-structure the array is saved in session
let's say, somewhere else in your businesslogic you need these session
data once more:
you initiate a variable with the recently saved session array
the PROBLEM now: the variable is initiated with the array NOT RESETTED
as defined in documentation an array assigned to a variable has to be
resetted
the problem exists also with php version 5.2.5
Reproduce code:
---------------
session_start();
$arrL =
array("test1","test2","test3","test4","test5","test6","test7","test8","test9","test10");
if(!isset($_SESSION['DATA'])){
$_SESSION['DATA']=$arrL;
}
$counter = 3;
$arrSessData = $_SESSION['DATA'];
while((list($index, $value) = each($arrSessData)) &&
($counter > 0) )
{
$arrSessData[$index] = '_test_' . $value;
$counter--;
}
//store changes in session
$_SESSION['DATA']=$arrSessData;
//somewhere else within the businesslogic, init local
variable and step
through
$arrSessDataProc = $_SESSION['DATA'];
while((list($index, $value) = each($arrSessDataProc)) ){
echo "<br>" . $index . ' ' . $value;
}
Expected result:
----------------
0 _test_test1
1 _test_test2
2 _test_test3
3 test4
4 test5
5 test6
6 test7
7 test8
8 test9
9 test10
Actual result:
--------------
4 test5
5 test6
6 test7
7 test8
8 test9
9 test10
