--EXPECTF--
Lets see what the Serializeable interface makes our object behave like...
myclass::__construct('Called by script') - note that it must not be called when unserializing
myclass::serialize()
myclass::unserialize('Value from serialize()')
object(myclass)#%d (0) {
}

And now magic PDO using fetchAll(PDO::FETCH_CLASS|PDO::FETCH_SERIALIZE)...
myclass::unserialize('Data fetched from DB to be given to unserialize()')
object(myclass)#%d (0) {
}
myclass::unserialize('Data fetched from DB to be given to unserialize()')
object(myclass)#%d (0) {
}

And now PDO using setFetchMode(PDO::FETCH:CLASS|PDO::FETCH_SERIALIZE) + fetch()...
myclass::unserialize('Data fetched from DB to be given to unserialize()')
object(myclass)#%d (0) {
}
done!
