嘿伙计们。我有个问题。当我运行此代码时，我收到此错误：

( ! ) Fatal error: Uncaught exception 'PDOException'

带有消息

'invalid data source name' in C:\wamp\www\moviedata.php on line 3 ( ! ) PDOException: invalid data source name in C:\wamp\www\moviedata.php on line 3

如果有人可以帮我解决这个问题，我会很感激。

Answer 1

您正在致电

mysql_select_db ( "moviesite");

但这不是PDO的一部分，它是MySQL的一部分。

你应该这样做：

$DB_HOST = "";
$DB_NAME = "";
$DB_PASS = "";
$DB_PORT = 3306;
$DB_USER = "";

$dsn = "mysql:host=" . $DB_HOST . ";port=" . $DB_PORT . ";dbname=" . $DB_NAME . ";charset=utf8";

$db_connection = new PDO($dsn, $DB_USER, $DB_PASS);

Answer 2

不要混合使用mysql_ *函数和PDO 检查PDO_MySQL DSN。

的语法

<?php
$pdo = new PDO('mysql:host=localhost;dbname=moviesite;charset=utf8', 'username', '', array(
    PDO::ATTR_EMULATE_PREPARES=>false,
    PDO::MYSQL_ATTR_DIRECT_QUERY=>false,
    PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION
));

$pdo->exec("
    INSERT INTO movie
        (movie_id, movie_name, movie_type, movie_year, movie leadactor, movie_director)
    VALUES
        (1, 'Bruce Almighty', 5 , 2003, 1, 2),
        (2, 'Office Space', 5, 1999, 5, 6),
        (3, 'Grand Canyon', 2, 1991, 4, 3)
");
// and so on and on
