title: In Codeigniter 4, how to display database name and table prefix?
body: <p>So far in codeigniter 3 we can get database name and table prefix <em>(as mentioned in <code>config/database.php</code>)</em> from the below code lines:</p>
  <pre><code>echo $this-&gt;db-&gt;database;
  echo $this-&gt;db-&gt;dbprefix('emp_table');
  </code></pre>
  <p>Now how can we call these values in Codeigniter 4?</p>
