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 (
$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();
?>

Example #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($stmt399);

    
/* 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);
?>
