我正在尝试使用TCPDF库来获得支持阿拉伯字母的PDF文件。我创建了一个表并从MYSQL数据库中获取数据。

我可以使用我的代码创建的表。检索到的阿拉伯数据如下：我该如何解决？
答案 0 :(得分：0)
您的问题非常简单，您需要选择正确的数据库编码并使用它进行查询，但在此之前，我认为我有责任告诉您您不必使用“mysql”你必须使用“mysqli”，现在让我们来解决问题：
在mysqli connect之后执行此操作 $ db-＆gt; set_charset（“utf8”）; 或者如果你仍然 想使用mysql使用这个 mysql_set_charset（“utf8”）;
以下是编辑过的代码：
connect($host='xxxx',$username='xxxx',$passwd='xxxx',$db='xxxxx')
{
$this->conn = mysql_connect($host,$username,$passwd) or die( mysql_error() );
mysql_select_db($db,$this->conn) or die( mysql_error() );
mysql_set_charset("utf8");
return true;
}
但是，就像我告诉你的那样，你是以错误的方式做到的，使用mysqli并且在没有时间的情况下使用完整的OOP并且在其他时间没有！
