title: PHP Document management
body: <p>I am looking for a mature PHP-based, preferably Open Source, Document management solution.</p>
  
  <p>Requirements:</p>
  
  <ul>
  <li>Manage documents, preferably in a folder structure</li>
  <li>Clean architecture</li>
  <li>Half-way nice-looking interface (I can customize but need a clean basis)</li>
  <li>Can fulltext index PDF, OpenOffice and ideally MS Office formats</li>
  <li>Multi-user capable</li>
  <li>Must be a browser-based web app, no Java clients etc.</li>
  <li>Self-hosted solution</li>
  </ul>
  
  <p>Nice to haves:</p>
  
  <ul>
  <li>An API to read / write documents would be great</li>
  <li>PHP5 based architecture</li>
  <li>Versioning (Storage of multiple versions of a document)</li>
  <li>Image thumbnails</li>
  <li>Tagging</li>
  </ul>
  
  <p>I am aware of</p>
  
  <ul>
  <li><a href="http://www.knowledgetree.com/" rel="nofollow noreferrer">KnowledgeTree</a> (about to do a test install)</li>
  <li><a href="http://www.opendocman.com/features/" rel="nofollow noreferrer">OpenDocMan</a> (very interesting, about to do a test install)</li>
  </ul>
  
  <p>and would appreciate any additional hints and links to related projects - also in the direction of Asset Management for advertising agencies and such. For a brilliant, totally outstanding killer application that does most things out of the box I would also be ready to go beyond PHP (but it has to be a web app).</p>
  
  <p>I checked through <a href="https://stackoverflow.com/search?q=php+document+management">the dupes</a> but found no question going into the right direction.</p>
