Bug description:Crash when using unserialized DatePeriod instance
Description:
------------
DatePeriod class does not have the serialization/unserialization logic
implemented. Therefore, when unserialized instance is used, script
crashes.
This is result of serializing the DatePeriod instance:
O:10:"DatePeriod":0:{}
unserialize() wents fine as well, but when I call foreach() on unserialized
instance, the script crashes.
Test script:
---------------
$dp = new DatePeriod(new DateTime('2010-01-01 UTC'), new
DateInterval('P1D'), 2);
echo "Original:\r\n";
foreach($dp as $dt) {
echo $dt->format('Y-m-d H:i:s')."\r\n";
}
echo "\r\n";
$ser = serialize($dp); // $ser is: O:10:"DatePeriod":0:{}
// Create dangerous instance
$dpu = unserialize($ser); // $dpu has invalid valuesâ¦
echo "Unserialized:\r\n";
// â¦which leads to CRASH:
foreach($dpu as $dt) {
echo $dt->format('Y-m-d H:i:s')."\r\n";
}
Expected result:
----------------
Original:
2010-01-01 00:00:00
2010-01-02 00:00:00
2010-01-03 00:00:00
Unserialized:
2010-01-01 00:00:00
2010-01-02 00:00:00
2010-01-03 00:00:00
Actual result:
--------------
PHP crashes on the "unserialize" line.
