/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
if ($result = $mysqli->query($query)) {
/* seek to row no. 400 */
$result->data_seek(399);
/* 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();
?>
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);
}
/* close connection */
mysqli_close($link);
?>
The above examples will output:
