Here's the shortest possible example script I came up with,
which does exactly same as your multiple scripts plus
shows what really happens:
<?php
class data {var $f;}
session_start();
$phase = isset($_GET['phase']) ? $_GET['phase'] : 1;
switch ($phase) {
case 1:
$_SESSION['foo'][0] = new data;
$_SESSION['foo'][0]->f = 1;
$_SESSION['foo'][1] = new data;
$_SESSION['foo'][1]->f = 2;
header("Location: test_web.php?phase=2");
exit(1);
break;
case 2:
$_SESSION['bar'] = new data;
$_SESSION['bar']->f = 3;
header("Location: test_web.php?phase=3");
exit(1);
break;
case 3:
$_SESSION['foo'][0] = $_SESSION['bar']; // Here be bug
header("Location: test_web.php?phase=4");
exit(1);
break;
case 4:
$_SESSION['bar'] = 'foo';
header("Location: test_web.php?phase=5");
exit(1);
break;
case 5:
echo '<pre>';
var_dump($_SESSION);
echo '</pre>';
break;
}
?>
Output is this:
array(2) {
["foo"]=>
array(2) {
[0]=>
&string(3) "foo"
[1]=>
object(data)(1) {
["f"]=>
int(2)
}
}
["bar"]=>
&string(3) "foo"
}
Result: ['bar'] became a reference to ['foo'][0]
(Does NOT happen when using arrays instead of object)
