我有用于发布到 idibu API（英国的工作委员会 API）的 XML 数据。我已经使用他们的测试 POST 数据进行了成功的通话。这里是：

为简单起见，我将 API 数据设置为两种格式中的后者（标准 XML）。例如，对于 advertcompletionemail 将是：
echo "<advertcompletionemail>".$advert_email."</advertcompletionemail>";
信息必须进行编码，以便在我完成设置后最终将其发送到 API。idibu 文档说它需要被编码为 iso-8859-1，这就是我假设的第一个代码块。我尝试将整个 XML 数据设置为字符串 ($str)，然后运行：
echo "htmlentities($str)";
或者
echo "htmlentities($str, ENT_QUOTE, ISO-8859-1);
但两者都不起作用。我还尝试了 utf8_decode($str) （和 utf8_encode($str) 即使我很确定这不是正确的功能）但它没有用。谁能帮我弄清楚如何将此 XML 编码为正确的格式？谢谢你的帮助！
