get RSS feed into php array - possible?
提问by Haroldo
I want to parse an existing RSS feed from another website with php and then store certain parts of it in a mysql database.
我想用 php 解析来自另一个网站的现有 RSS 提要，然后将其中的某些部分存储在 mysql 数据库中。
I'm very competent with php and mysql but have never worked with rss feeds before, where should i start?
我非常擅长 php 和 mysql，但以前从未使用过 rss 提要，我应该从哪里开始？
- is there an equivalent to file_get_contents() for getting rss into php?
- are rss feeds broken down into xml/microdata or do i need to use regex to grab bits?
- 是否有等效于 file_get_contents() 的用于将 rss 导入 php？
- RSS 提要是否分解为 xml/microdata 或者我是否需要使用正则表达式来获取位？
cheers!
干杯！
