$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
 
/* 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:

City: Benin City  Countrycode: NGA
