Example #1 Object oriented style


<?php
/* 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());
    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();
?>

Example #2 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);
?>
