php - 使用 simplexml 获取 RSS 并在 DB 中插入给了我奇怪的字符'

Question

例如以下提要：http ://blog.optimizely.com/feed/ 有一个标题元素，如下所示：

<title>
Lessons in Marketing from Daft Punk (Hint: It&#8217;s 
  Not Just About Getting Lucky)
</title>

这个标题最终出现在我的数据库中，如下所示：

愚蠢朋克的营销课程（提示：这不仅仅是为了幸运）

这些表设置为使用 UTF-8

$rss = simplexml_load_file($item['Rss']);
$items=$this->getItems($rss);
foreach($items as $article){
    if($this->shouldInsert($article)){
        $this->insertItem($article,$item["id"]);
    }else{
        var_dump("skipping:");
        continue 2;
    }
}
    //the getItems function:
public function getItems($xml){
    if(count($xml->channel)!==0){
        return $xml->channel->item;
    }
    if(count($xml->feed)!==0){
        return $xml->feed->entry;
    }
    if(count($xml->entry)!==0){
        return $xml->entry;
    }
    return [];
}
    //insertItem:
public function insertItem($item,$sourceID){
    $dbh = new PDO('mysql:host=localhost;dbname=db', 'usr', 'pwd');
    $title=(string) $item->title;
    $url=$this->getLink($item);
    $pubDate=$this->getPubDate($item);//pubdate is optional
    if($pubDate!==false){
        $pubDate=new DateTime($pubDate);
        $pubDate=date('Y-m-d H:i:s e',$pubDate->getTimestamp());
    }
    $now=new DateTime();
    $inserted=date('Y-m-d H:i:s e',$now->getTimestamp());
    $query="insert into tblItems (title,url,clicks,pubdate,inserted,sourceid)" .
     "values ("
     .$dbh->quote($title)
     .",".$dbh->quote($url)
     .",0"
     .",".$dbh->quote($pubDate)
     .",".$dbh->quote($inserted)
     .",".$sourceID.")";
    $stm=$dbh->query($query);
    $dbh=null;
}

改变这个

$dbh = new PDO('mysql:host=localhost;dbname=db', 'usr', 'pwd');

至

$dbHandle = new PDO("mysql:host=localhost;dbname=db;charset=utf-8", 'usr', 'pwd',
                    array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
