title: Development environment with multiple developers on a single application
body: <p>I'm looking for a good way to optimise/improve the way my colleagues and I work on our applications.</p>
  
  <p>We currently all work in PhpStorm on a MacBook Pro (2016), an Ubuntu server in our network and a working copy mapped on a SMB share to our machines (we sometimes edit the same files, making this inconvenient). We use Git as source control and have 1 branch we all work in.</p>
  
  <p>We are noticing performance problems using PhpStorm over the network share, our application is quite large and having PhpStorm index everything makes it freeze and feel non-responsive all the time.</p>
  
  <p>We're looking for a way to improve the way we work, streamlining the development of our application and removing the performance problems we have with the network share/working copy combination.</p>
  
  <p>We are thinking of each having a working copy locally on our machines, having a virtualised webserver (Vagrant) and all running the application separately from each other. This would fix the issues with the network,  however it would bring other problems, if I, for example, make database changes, these changes would also have to be done on my colleague's working copy. </p>
  
  <p>Also, we make changes in the same files all the time, the last thing we want is fixing file conflicts every time we make change, nevertheless having to pull every commit another developer makes during the day, plus having to do their database changes manually.</p>
  
  <p>TL;DR, what is a good way to work on 1 application with 3 developers.</p>
