连接到MYSQL时出错

Question

这是config.php文件

<?php

error_reporting(E_ALL ^ E_NOTICE);

/*=========== Database Configuraiton ==========*/

$db_host = "localhost";
$db_user = "test";
$db_pass = "test";
$db_name = "dbtest";


/*=========== Website Configuration ==========*/

$defaultTitle = 'testing';
$defaultFooter = date('Y').' &copy; testing';

?>

这是对config.php的引用

<?php


require_once "includes/config.php";
require_once "includes/connect.php";
require_once "includes/helpers.php";



header('Cache-Control: max-age=3600, public');
header('Pragma: cache');
header("Last-Modified: ".gmdate("D, d M Y H:i:s",time())." GMT");
header("Expires: ".gmdate("D, d M Y H:i:s",time()+3600)." GMT");

?>

Connect.php如下

<?php

/*
        The login details are taken from config.php.
*/

try {
    $db = new PDO(
        "mysql:host=$db_host;dbname=$db_name;charset=UTF-8",
        $db_user,
        $db_pass
    );

    $db->query("SET NAMES 'utf8'");
    $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e) {
    error_log($e->getMessage());
    die("A database error was encountered");
}


?>

有没有人看到这个代码的问题？我从connect.php收到错误消息"遇到数据库错误"我需要另一组眼睛,因为我的所有信息看起来都正确,我无法在代码中看到错误.谢谢.

Answer 1

你简单地将UTF-8改为utf8 ..

try {
      $db = new PDO(
              "mysql:host=$db_host;dbname=$db_name;charset=utf8",
              $db_user,
              $db_pass
            );

Answer 2

一旦尝试直接使用您的凭据，而不是使用它们作为变量。

还尝试使用以下进行调试：

catch(PDOException $e) {
    error_log($e->getMessage());
    die("A database error was encountered -> " . $e->getMessage() );
}

让我知道它是否有效。
