Bug #56512 Can't PDO object be serialized?
Submitted: 2005-08-26 20:30 UTC Modified: 2005-09-10 13:49 UTC
From: osmium at 163 dot com Assigned: wez (profile)
Status: Closed Package: PDO (PECL)
PHP Version: 5_1 CVS-2005-08-26 (dev) OS: Windows Server 2003
Private report: No CVE-ID: None

When using a PDO connection object unserialize from a serialized string, PHP crashed. Error message: "Application Failure  Apache.exe in php5ts.dll at offset 0012bb10".

Is it really a bug? My PHP version is 5.1.0RC1.

Reproduce code:
$connection = new PDO("mysql:dbname=test;host=localhost", "root", "root");
$connection = unserialize(serialize($connection));
$stmt = $connection->query("SELECT * FROM users");
$connection = null;

Expected result:
The code worked well

Actual result:
The browser said "can not find server" and PHP crashed with message "Application Failure  Apache.exe in php5ts.dll at offset 0012bb10".

PDO can't be serialized.  I've added some safety checks that will prevent the crash to the code in CVS.
Thanks for your report.
