Serialize object from within

I have the class testClass which has the method save. This method saves object to a database. But it needs to serialize object before saving. How can I serialize object from within the class to do that?

class testClass {
    private $prop = 777;
    public function save() {
        $serializedObject = serialize(self);
        DB::insert('objects', array('id', 'object'))
                ->values(array(1, $serializedObject))
                ->execute();
    }
}

serialize(self) obviously doesn't work.

First, you need to pass $this to serialize() rather than self:

$serializedObject = serialize($this);

Secondly, unless you are not implementing the Serializable interface (as from PHP 5.1 ) you need to implement the "magic method" __sleep() in order to serialize private or protected properties:

public function __sleep() {
    return array('prop');
}

This manual page about serializing objects should help further.
