Simple PHP Script

I'm looking to input a list of RSS feed URLs and have the script output the date of the last post.

This data needs to be in a table that I can sort.

Here is an example, but the example doesn't work very well and gives me errors.

Here is a list of example input URLs. I would input these and expect the script to output the URL and date.

http://home-design.science/feed/
http://freefishfacts.com/feed/
http://www.oceanfloorstore.com/feed/
http://saltwaterfishkeeping.com/category/saltwater-fish/feed/
http://ocalaaquariums.com/feed/

Let me know if you need more info. Looking to get this done ASAP.

I whipped something up real quick, inbox me to see if it works for you.

your request is quite vague but if it is what i think it is then it should be easy.
