 /**
 * Example to send single push notifications.
 *
 * For easy setup we use the SQLite dataprovider and set the database file
 * located in the same directory as this script.
 *
 * First you should open PNTestClient.html in your browser and click the
 * [Subscribe] button to create a valis subscription in your database.
 *
 * Needed steps to send notification to all subscriptions stored in our database:
 * 1. Create and init dataprovider for database containing at least one valid subscription
 * 2. Set our VAPID keys (rename MyVapid.php.org to MyVapid.php ans set your own keys)
 * 3. Create and set the payload
 * 4. manuelly step through the Subscriptions...
 * 5. .. and push each of the notification by single call
 *
 * After the notification was pushed, a summary and/or a detailed log can be
 * retrieved from the server
 *
 * If you want to log several events or errors, you can pass any PSR-3 compliant
 * logger of your choice to the PNDataProvider- and PNServer-object.
 *
