title: base_url codeigniter solution
body: <p>I use the base url in code igniter like this:</p>
  
  <pre><code>&lt;a href="&lt;?=base_url()?&gt;../../includes/images/logo_fosss.png"&gt;
  </code></pre>
  
  <p>The above code runs correctly.</p>
  
  <p>But sometimes this code gives an error, and the code must be changed like this:</p>
  
  <pre><code>&lt;a href="&lt;?=base_url()?&gt;../../../includes/images/logo_fosss.png"&gt;
  </code></pre>
  
  <p>I've put a folder 'includes' in the root (same place level as application and system).</p>
  
  <p>What's wrong with my code?</p>
