title: Update MySql values with it's current value in php
body: <p>I have a column called name in a table info</p>
  
  <p>So I want to update that with it's current value, like this name + user_input. I tried with this code but not working</p>
  
  <pre><code>mysql_query("UPDATE info SET name = name + '$user_input' WHERE id='$user_id'");
  </code></pre>
