[BUG]: Cache\AdapterFactory - Get Key with value of zero returns NULL

[dz3n]

Describe the bug
Not able to set value of zero through Phalcon\Cache\AdapterFactory

To Reproduce

        $di->setShared(
            'cache',
            function () use ($config) {
                $serializerFactory = new SerializerFactory();
                $adapterFactory = new AdapterFactory($serializerFactory);
                $options = [
                    'host' => $config->redis->host,
                    'port' => $config->redis->port,
                    'index' => 1,
                    'lifetime' => 86400,
                    'prefix' => 'api-',
                ];

                $adapter = $adapterFactory->newInstance('redis', $options);

                return new Cache($adapter);
            }
        );

Provide minimal script to reproduce the issue

        $cache = Di::getDefault()->get('cache');

        $cache->set('key', 0);
        $result = $cache->get('key');
        var_dump($result); //return NULL;

Expected behavior
it should return int(0)

@dz3n Thank you for reporting this.

The issue appears when the if (!$content) { condition is true It will return the default value (null) at the time.

I am going to introduce a store structure that will allow checking for failures on the adapter (say apcu_store fails and returns false) vs. actual values.

More on this shortly.
