Bug #64724 [NEW]: Objects stored in Sessions sometimes get "lost".
From: php dot bugs at lippe-net dot de
Operating system: Debian Wheezy
PHP version: 5.4.14
Package: Session related
Bug Type: Bug
Bug description:Objects stored in Sessions sometimes get "lost".
Description:
------------
The "transactions" array of the $_SESSION variable is initialized only
once.
If you repeat the invocation of the script. After a while the array
contains some
elements that are no more Objects of "class S" but references (for example
r:5607;).
Test script:
---------------
<?php
class S implements \Serializable {
protected $data = [];
public function __construct() {
for ( $i = 0; $i <= mt_rand(4, 7); $i++ ) {
$this->data[] = mt_rand(0, 50);
}
}
public function serialize() {
return serialize($this->data);
}
public function unserialize($data) {
$this->data = unserialize($data);
}
}
session_name("testS");
session_start();
if ( empty($_SESSION["transactions"]) ) {
$_SESSION["transactions"] = [ new S(), new S(), new S(), new S() ];
}
echo serialize($_SESSION);
?>
Expected result:
----------------
Example (first call):
transactions|a:4:{i:0;C:1:"S":76:{a:8:
{i:0;i:9;i:1;i:24;i:2;i:23;i:3;i:46;i:4;i:29;i:5;i:4;i:6;i:44;i:7;i:14;}}i:1;C:1:"
S":51:{a:5:{i:0;i:11;i:1;i:45;i:2;i:12;i:3;i:10;i:4;i:21;}}i:2;C:1:"S":59:{a:6:
{i:0;i:47;i:1;i:5;i:2;i:40;i:3;i:35;i:4;i:29;i:5;i:14;}}i:3;C:1:"S":58:{a:6:
{i:0;i:20;i:1;i:20;i:2;i:7;i:3;i:44;i:4;i:7;i:5;i:27;}}}
Actual result:
--------------
Example (after some roundabout 50 calls):
transactions|a:4:{i:0;r:5607;i:1;r:5617;i:2;r:5624;i:3;r:5632;}
