title: new mysqli vs mysqli_connect
body: <p>What is difference between the new <code>mysqli</code> and <code>mysqli_connect</code>?
  I know that executing a query is different;
  <br />
  for example: <code>mysqli-&gt;query()</code> and <code>mysqli_query()</code>
  <br />
  Why are there two different types, what is the need for the difference?</p>
