关于我在这里尝试做什么的一点背景。对于这个项目，我正在使用Wordpress中其他人的API调用，基本上如果你的搜索没有显示任何显示错误，说明没有找到任何内容。
我没有编写大部分的PHP和API调用，但我把HTML放在一边。我很难搞清楚这一个。我认为在底部我可以添加else语句，它应该可以工作，但事实并非如此。
代码很长，所以这里有一个链接，希望有更多PHP知识的人可以帮助我在这里，在最底层你可以看到我的其他声明。

不要在块中混合使用这两种语法。我们希望此代码返回语法错误。
当前代码看起来遵循以下模式：
if (!empty($objSearchData['Providers'])) {
} else: {
}
其他冒号（else:）后的冒号无效。
只需在else之后删除冒号
if (!empty($objSearchData['Providers'])) {
} else {
}
文件末尾的其他内容应如下所示：
<?php else: ?>
<h2>No Content Avalable</h2>
<?php endif; ?>
