title: How to make "PHP Explorer" (project explorer?) area persistent between sessions in eclipse/PDT?
body: <p><strong>PHP Explorer</strong> is the eclipse PDT tab (the leftmost in standard configuration) where you can browse the folders of your project. I believe the same tab in standard eclipse is called "Project Explorer" but I am not sure.</p>
  
  <p>What happens to me is that when I close and reopen eclipse, although the files that were open at close time are still open on relaunch of eclipse, all <strong>my folder hierarchy in PHP Explorer (where I had various folders open at close time) is displayed collapsed</strong>.</p>
  
  <p>Is there away to tell eclipse to reopen all my folders the way they were at close time?</p>
  
  <p>Thank you in advance for your time!</p>
