php - META 描述和 Facebook

Question

这是我的动态标题和元描述更新代码；

$titlecek=mysql_query("SELECT bahisisim,bahisiaciklama,URL FROM bahis WHERE id='$bahisid'");
$titlecekx=mysql_fetch_array($titlecek);
echo "<title>" . mb_strtolower($titlecekx[0],'UTF-8') . "</title>";
echo '<META NAME="Description" CONTENT="' . mb_strtolower($titlecekx[1],'UTF-8') . '">';

但是当我尝试在 Facebook 上分享我的页面时，它看起来像；

http://666kb.com/i/c6st3ke4u4hqaem42.gif

顺便说一句，它的 HTML 代码在输出时是这样的；

<title>bu bahise gelen evet says tek say olacak</title><META NAME="Description" CONTENT="bu bahise 2 gün içerisinde gelen evet oyu sayısı tek sayı olacak. (ilkokullu editi: 2'nin katları çift sayıdır, 0 çift sayıdır)">

我该如何解决这个问题？

每次更改元标记时，您都必须通过 Facebook Debugger 运行您的 URL以确保 Facebook 丢弃它缓存的元标记版本。

取自Facebook Open Graph Protocol documentation ，在“编辑元标记”部分下 -

For the changes to be reflected on Facebook, you must force your page to be scraped. The page is scraped when an admin for the page clicks the Like button or when the URL is entered into the Facebook URL Linter Debugger.
