范例
例子 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();
}
$mysqli->query("CREATE TABLE myCountry LIKE Country");
$mysqli->query("INSERT INTO myCountry SELECT * FROM Country");
$query = "SELECT Name, Code FROM myCountry ORDER BY Name";
if ($stmt = $mysqli->prepare($query)) {
/* drop table */
$mysqli->query("DROP TABLE myCountry");
/* execute query */
$stmt->execute();
printf("Error: %s.\n", $stmt->sqlstate);
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
?>

例子 2. Procedural style
<?php
/* Open a connection */
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
mysqli_query($link, "CREATE TABLE myCountry LIKE Country");
mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");
$query = "SELECT Name, Code FROM myCountry ORDER BY Name";
if ($stmt = mysqli_prepare($link, $query)) {
/* drop table */
mysqli_query($link, "DROP TABLE myCountry");
/* execute query */
mysqli_stmt_execute($stmt);
printf("Error: %s.\n", mysqli_stmt_sqlstate($stmt));
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
