title: PHP rename folder
body: <p>I have a photo gallery with a simple ul list of categories.
  The categories are folders on my server.
  If a folder is named "Ödla" then the category is named "Ödla" too.
  Is it possible to replace "Ö" in "Ödla" with "o" only on the category and not the actual folder on the server. I don´t want to use mysql.</p>
  
  <p>I hope you understand what I mean. </p>
  
  <p>Edit: The categorys is only textlinks</p>
  
  <ul>
    <li>Ödla</li>
    <li>Category 2</li>
  </ul>
  
  <p>And in this example there are two folder on my server named "Ödla" and "Category 2"</p>
  
  <p>I just want to rename the category links, not the folder.</p>
