title: PHP/MySQLI select multiple columns
body: <p><strong>Hello all,</strong></p>
  
  <p>This query below contains the prepared statement that I would like to have mysqli processed</p>
  
  <pre><code>"SELECT password, salt FROM accounts WHERE username=?"
  </code></pre>
  
  <p>So far there seems to be no documentation on how fetch_array() works in OO-style with prepared statements. The closest thing I can find is <a href="http://php.net/manual/en/mysqli-result.fetch-array.php" rel="nofollow">http://php.net/manual/en/mysqli-result.fetch-array.php</a> </p>
  
  <p>Is there a particular "correct" way of doing it with mysqli prepared statements (the OO way)? thanks!</p>
