Example

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($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);
?>

The above examples would produce the following output:

City: Benin City  Countrycode: NGA
