MySql+php在数据库中插入特殊字符（utf8）

我得到了这段代码，它从Steam Web Api中获取数据，并将数据打印出来，然后插入数据库。我的问题是web api中的名称personaname可能有特殊字符，如俄语字符、希腊语字符等。我用utf8配置了php，所以当我直接从api打印到php代码时，这些字符没有问题，但当我尝试将它们插入数据库时，它们被损坏了？？？？？或者说是o？f？？？。我用utf8 utf8_unicode_ci配置了PDO，mysql也是如此。我尝试使用htmlspecialchars和utf8_编码，但没有成功。对不起，我的英语不好

$steamkey = "x";

   $api = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?       key=".$steamkey."&steamids=".$id_banuser_final;

curl_setopt($ch1, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch1, CURLOPT_URL,$api);

如何查看损坏的数据库条目？此外，如果您的connect_db函数无法连接，那么它应该退出。我检查了SQLyog中的条目，然后在php中添加了一个SELECT，用于比较API中的personame和数据库中的personame。关于连接数据库你是说我需要在捕获中添加一个中断？太酷了。我只是问，无论您使用什么来查看条目，都需要与UTF兼容，但我可以看到，您已经通过直接从API显示结果，然后通过SELECT来完成这项工作。关于你的函数，我不会捕捉到异常。在插入db之前，如何将变量转换为utf8：你的profiles表是什么字符集/排序规则？它的专栏呢？这可能值得一读~

function connect_db()
{
    try
    {
        $connection = new PDO('mysql:host=localhost;dbname=d2bd;charset=utf8', 'root', '123123');
        $connection->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
        $connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $connection->setAttribute(PDO::ATTR_PERSISTENT, true);
        $connection->setAttribute(PDO::MYSQL_ATTR_INIT_COMMAND, "SET NAMES 'utf8' COLLATE     'utf8_unicode_ci'");
    }
    catch (PDOException $e)
    {
        // Proccess error
        echo 'Cannot connect to database: ' . $e->getMessage();
    }

    return $connection;
}
