title: Codeigniter $this->db->get(), how do I return values for a specific row?
body: <p>Say I have a database table with three columns: ID, Name, and Age.
  I need to find the user with a specific (unique) ID, and then return the age. Currently, I am using the following code</p>
  
  <pre><code>$this-&gt;db-&gt;where('id', '3');
  $q = $this-&gt;db-&gt;get('my_users_table');
  </code></pre>
  
  <p>How do I go about getting the age for this user? I think I have to use</p>
  
  <pre><code>$q-&gt;result()
  </code></pre>
  
  <p>But not sure how to use it with one row.</p>
