php - PDOException 没有被捕获？

Question

我在 PHP 中收到以下错误:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'localhost' (10061)' in C:\xampp\htdocs\project\Service\Database.class.php:26 Stack trace: #0 C:\xampp\htdocs\project\Service\Database.class.php(26): PDO->__construct('mysql:host=loca...', 'root', '', Array) #1 C:\xampp\htdocs\project\Service\Database.class.php(54): Service\Database::initialize() #2 C:\xampp\htdocs\project\index.php(15): Service\Database::getHandler() #3 {main} thrown in C:\xampp\htdocs\project\Service\Database.class.php on line 26

错误本身不是问题，我故意终止了MySQL Windows 中的服务来查看发生了什么(我正在使用 XAMPP )。问题是我无法捕获 PDO 的异常对象抛出异常，我不知道为什么。

try {
    $host       = "localhost";
    $dbname     = "project";
    $userName   = "root";
    $password   = "";
    $charset    = "utf8";
    $dsn        = "mysql:host=$host;dbname=$dbname;charset=$charset";

    $driverOptions = array(
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES $charset"
    );

    // This is the line that supposedly throws the exception (LINE 26):
    $dbh = new PDO($dsn, $userName, $password, $driverOptions);

    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    self::setHandler($dbh);
} catch (PDOException $e) {
    die("CATCHED"); // This line is never reached
} catch (Exception $e) {
    die("CATCHED"); // nor this one.
}

我在这里缺少什么？

我唯一能想到的是，如果您位于命名空间类中，则应该使用 \PDOException 而不是 PDOException。
