php – Simplepie RSS提供给MySQL数据库服务器
作者：互联网
我目前正在使用Simplepie来提取我的RSS源,如下面的配置所示.我想将$url移动到我的数据库,因为我的网站加载速度太慢.我将每个url作为网站名称的键值对.我想保留这种关联,因为我使用例如“abc”将图像拉出我的目录,我用它来为每个Feed设置样式,如下面的foreach循环中所示.
我的问题是,由于我不清楚数组和表如何协同工作,我将如何重写此脚本以同样的方式使用数据库？
我还要提一下,我已经在MySQL中创建了一个带有“id”“name”和“url”行的表.任何澄清都会有所帮助.

解决方法:
我在一些项目中使用SimplePie,这是我减少页面加载时间的方法：我缓存结果.
这个流程大约是这样的：
>我把PHP代码提取到Feed并在一个地方生成HTML.这个脚本基本上与你的相同.假设我将该脚本重命名为feed-fetcher.php
>在此脚本中,我添加了一个功能,可将生成的HTML保存到同一文件夹中的index.html之类的内容中.实际上,在我想要访问feed项内容的根文件夹中,以便于(或将来)阅读.
>我设置了一个每20分钟左右取一次进给的cron作业.
>当我想读取提取的内容时,我会转到存储在上面提到的.html文件中的缓存内容的URL.因此,我的页面加载速度非常快,因为我不需要等待提取和处理我要检查的每个提要.
此解决方案不需要任何数据库.但是,当然您仍然可以使用数据库将以HTML格式编写的获取内容存储为字符串,或任何其他适合您需求的类型.
这是你想要的？
