您好！我正在使用PHP制作一个实时评分网站。但是，当我使用此代码并运行它时，我得到一个空白页面。我希望我能自己找到错误，但现在我不能。如果有人知道错误在哪里并帮助我，我会很高兴。提前谢谢!!!

Answer 1

这是错误的

public_static_function getInstance() {

应该是

public static function getInstance() {

如果您有空白页面（这意味着您有错误），请添加error_reporting(E_ALL)

Answer 2

即使修复了，这也行不通：

public static function getInstance() {
    static $instance;
    $class = $title;
    ...
}

此外，我们有simpleXML_load_str()来处理RSS（或其他XML）字符串。

我认为你想要的是一种处理RSS提要的好方法。看看this post about RSS feeds

祝你好运！
