title: Use Firebase Database with MySQL
body: <p>I'm working on an android application project which needs to retrieve/store data with the offline capability(which Firebase does the best) but my client needed that the data should be stored in MySQL for use in CRM application too.</p>
  
  <p>So I wanted to ask is there a way to sync Firebase with MySQL? I'm currently used Firebase JS Library combined with PHP insert command which may cause a problem if there's no internet connection or SQL server is down.</p>
  
  <p>Thanks!</p>
