title: Deleting a File using php/codeigniter
body: <p>I would like to delete a file that is found in my localhost.</p>
  
  <pre><code>localhost/project/folder/file_to_delete
  </code></pre>
  
  <p>I'm using codeigniter for this.</p>
  
  <p>I would like to use the unlink() function in php but I really can't understand how to use it.</p>
