title: What PHP Blogging Software Should I Choose
body: <p>I am thinking of starting a blog, which I would like integrated into my existing website. I come back empty handed from googling for a comparison of blogging software written in PHP.</p>
  
  <p>My requirements:</p>
  
  <ul>
  <li>Simple but not rudimentary (not a result of a 15 minute CodeIgniter tutorial)</li>
  <li>Quality source code (I'd like to be able to learn from it and maybe change it)</li>
  <li>Prefer PHP5 over PHP4</li>
  <li>Work with MySQL</li>
  <li>Easy to integrate into an existing website (I don't want it to be a separate application with a different look and feel under a "blog" directory</li>
  <li>Run under safe_mode</li>
  </ul>
  
  <p>Built-in or easy-to-add source code highlighting would be a plus.</p>
