范例

Example #1 面向对象风格

<?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();
?>

Example #2 过程化风格

<?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 */
mysqli_close($link);
?>

以上例程会输出:

Error: 42S02.
