php - MySQLi，PHP-尝试{…}捕获(…){…}不起作用

Question

我正在尝试使用mysql捕获php7上的连接错误，但无法正常工作...

我不明白什么是不正确的:我使用的这段代码的类似部分也正常工作...

它必须是我忘记的基本细节...
我需要抛出$this->MyErrorFunction($e)
有人可以帮忙吗？

public function connect($credentialset) {
    #$this->driver = new \mysqli_driver();
    #$this->driver->report_mode = MYSQLI_REPORT_ALL;
    mysqli_report(MYSQLI_REPORT_STRICT); 
    try {
        $this->conn->real_connect(
                isset(self::$credentials[$credentialset]['host'])       ? self::$credentials[$credentialset]['host']        : ini_get("mysqli.default_host"),
                isset(self::$credentials[$credentialset]['user'])       ? self::$credentials[$credentialset]['user']        : ini_get("mysqli.default_user"),
                isset(self::$credentials[$credentialset]['password'])   ? self::$credentials[$credentialset]['password']    : ini_get("mysqli.default_pw"),
                isset(self::$credentials[$credentialset]['database'])   ? self::$credentials[$credentialset]['database']    : "",
                isset(self::$credentials[$credentialset]['port'])       ? self::$credentials[$credentialset]['port']        : ini_get("mysqli.default_port"),
                isset(self::$credentials[$credentialset]['socket'])     ? self::$credentials[$credentialset]['socket']      : ini_get("mysqli.default_socket"),
                isset(self::$credentials[$credentialset]['flag'])       ? self::$credentials[$credentialset]['flag']        : null
        );
        $charset = isset(self::$credentials[$credentialset]['charset']) ? self::$credentials[$credentialset]['charset'] : 'utf8mb4';
        $this->conn->set_charset($charset);
    } catch (Exception $e) {
        $this->MyErrorFunction($e);
    }
}

Fatal error: Uncaught mysqli_sql_exception: Access denied for user 'myinvaliduser'@'10.241.84.65' (using password: YES) in /oxygen-v2/php-bin/datadrivers/mysqlz/mysqlz.php on line 77

我确定错误只是愚蠢的事情!

解决了替换这段代码的问题:

} catch (Exception $e) {
    $this->MyErrorFunction($e);
}

通过此代码:

} catch (\mysqli_sql_exception $e) {
    $this->MyErrorFunction($e);
}

代替 Exception，我需要在主命名空间“ mysqli_sql_exception”中抛出 \。
