Using prepared statements there is no `fetch_array()`. Use `mysqli_stmt::fetch()` instead or to fetch multiple records use `mysqli_stmt::fetchAll()`
<br />Check the manual: [mysqli_stmt::fetch()](http://www.php.net/manual/en/mysqli-stmt.fetch.php) or [mysqli_stmt::fetchAll()](http://php.net/manual/en/mysqli-result.fetch-all.php)
