title: Creating a web app that can work offline, store data and then sync it to remote MySQL when online?
body: <p>I am looking to create a web app written in PHP / MySQL.  It will be used to collect data on houses by staff walking around a neighbourhood.  There may be places where they have little to no cell signal, so I need a way to allow them to still view the web app when offline, as well as store the data they are submitting, to be inserted to the MySQL database once their phone has a signal / wi fi.</p>
  
  <p>Is something like this even possible?</p>
