Examples
Example 20.162. Object oriented style

$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'world');
/* check connection */
if (mysqli_connect_errno()) {
printf('Connect failed: %s\n', mysqli_connect_error());
exit();
}
$query = 'SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20';
if ($stmt = $mysqli->prepare($query)) {
/* execute query */
$stmt->execute();
/* store result */
$stmt->store_result();
printf('Number of rows: %d.\n', $stmt->num_rows);
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
?>
Example 20.163. 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();
}
$query = 'SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20';
if ($stmt = mysqli_prepare($link, $query)) {
/* execute query */
mysqli_stmt_execute($stmt);
/* store result */
mysqli_stmt_store_result($stmt);
printf('Number of rows: %d.\n', mysqli_stmt_num_rows($stmt));
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
?>
