title: PHP Header move up one directory?
body: <p>How do I specify a file redirect to a file one level above the current file in PHP? Here is my schematic so far:</p>
  
  <pre><code>-landing.html
  -ajax
    -checkLogin.php 
  </code></pre>
  
  <p><code>checklogin.php</code>has the following code in it:</p>
  
  <pre><code>header("location:dashboard.html");
  </code></pre>
  
  <p>This obviously doesn't work since <code>landing.php</code> is one level above. How can I select a file one directory above? I already tried <code>..landing.php</code>, but seems like it will only take filenames.</p>
