Пример 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();
}
$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
if ($stmt = $mysqli->prepare($query)) {
/* execute query */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($name, $code);
/* store result */
$stmt->store_result();
/* seek to row no. 400 */
$stmt->data_seek(399);
/* fetch values */
$stmt->fetch();
printf ("City: %s Countrycode: %s\n", $name, $code);
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
?>

Пример 2. Procedural style
<?php
/* Open a connection */
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
if ($stmt = mysqli_prepare($link, $query)) {
/* execute query */
mysqli_stmt_execute($stmt);
/* bind result variables */
mysqli_stmt_bind_result($stmt, $name, $code);
/* store result */
mysqli_stmt_store_result($stmt);
/* seek to row no. 400 */
mysqli_stmt_data_seek($stmt, 399);
/* fetch values */
mysqli_stmt_fetch($stmt);
printf ("City: %s Countrycode: %s\n", $name, $code);
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
?>
