/* Open a connection */
$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'world');
/* check connection */
if (mysqli_connect_errno()) {
 printf('Connect failed: %s\n', mysqli_connect_error());

 /* fetch row */
 $row = $result->fetch_row();
 printf ('City: %s Countrycode: %s\n', $row[0], $row[1]);
 /* free result set*/
 $result->close();
}
/* close connection */
$mysqli->close();
?>

Example 20.178. Procedural style

<?php
/* Open a connection */
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'world');
/* check connection */
if (!$link) {
 printf('Connect failed: %s\n', mysqli_connect_error());
 exit();
}
$query = 'SELECT Name, CountryCode FROM City ORDER BY Name';
if ($result = mysqli_query($link, $query)) {
 /* seek to row no. 400 */
 mysqli_data_seek($result, 399);
 /* fetch row */
 $row = mysqli_fetch_row($result);
 printf ('City: %s Countrycode: %s\n', $row[0], $row[1]);
 /* free result set*/
 mysqli_free_result($result);
