title: Connecting to MySQL-database
body: <p>I'm creating a WWW-page in www.freehostingcloud.com. I created a database of the name sample. But how can I connect to it in MySQL and PHP? I saw from PHP.net that I should type </p>
  
  <pre><code>mysqli = new mysqli('localhost', 'my_user', 'my_password', 'my_db');
  </code></pre>
  
  <p>OK, so my_db=sample but what are those parameters 'localhost', 'my_user' and 'my_password'?</p>
