/**
 * Example to handle the HTTP-Request send from the ServiceWorker to
 * subscribe our notification service.
 *
 * For easy setup we use the SQLite dataprovider and set the database file
 * located in the same directory as this script.
 * You may use the MySQL dataprovider, just locate the database in a differnet
 * directory or write your own dataprovider for your project.
 *
 * Remember to adjust the path and name of the script in the service worker
 * (PNServiceWorker.js) when implementing the requesthandler in your own project.
 *
 * Set $bSendWelcome=true, to send a welcome notification to each user
 * newly subscribed our service, after the subscription was saved in
 * the database.
 *
 * If you want to log several events or errors, you can pass any PSR-3 compliant
 * logger of your choice to the dataprovider.
 *
 * THIS CODE IS INTENDED ONLY AS EXAMPLE - DONT USE IT DIRECT IN YOU PROJECT
