help with a news site pls

hello
i am trying to create a website that will automatically search a list of websites for a specific keyword every hour

i then need the website to display a link to any new pages that contain the keyword.

if this isn't clear then please visit http://www.newsnow.co.uk
as my intended site is very similar to that.

my problem is that i do not understand quite how to do this.

should i use a spider

or a database

or both

or something completely different

i am quite a newbie and any help would be greatly appreciated.

thank you

paul

what you could do instead is use an RSS feed.
The down side is you don't know what news you'll be getting.
The upside is you can choose a specific website, see if they have an RSS feed,
use it on your website and you'll get what ever news that website would have. This is the upside because you can choose specific topics like tech news, web news, health news ..stuff like that.

If you however want to do it your way then yes, it would seem you need a form of spider. But I say this is only from limited experience. You could probably write a php script that you could manually run, entering websites and keywords in links. You would probably want to parse a webpage, taking the link text and link url. Then simply pass those bits of info back to you. Where you could further add another function to create a sort of news feed. But compared to the RSS feed, this sounds like alot of work..?? Again, I have limited experience with this sort of thing.... thus can't be of much help in the long term.

PHP can do this, it can connect to sites, search for word matches on files, and return the results. It will take some programming knowledge though.
