KEyword Extraction and Echo?

[domainbanshee]

I am very new with PHP but am working on a url shortener program (in PHP) that I am trying to get to be able to place in the mata tag of the frame the keywords of the page it is redirecting so that any context-sensitive advertising and such on the frame will pull appropriate ads... I have some code snippets and such I am trying to figure out but essentially trying to get about the first 1000 characters of the referring page's keywords extracted and then cached so as to reduce server load, and then posted in the meta tag area of the framed area.

 

I dont know how to call the keyword script from the frame page, or really how to set it up to cache what data it extracts...

 

Any help at all in getting me on the right path is most appreciated!!!

 

Thanks!

If you are doing a URL shortening service, I take it that you are storing each item in the database. If so the cache is easy, add a column to the database for description then when the user submits their page you can fetch the pages infromation using either cURL or file_get_contents and parse it with preg_match for the meta tags and grab the data you need and store it in that column.

 

Hope that helps.
