I am building a web app for keywords research. Mainly what it does is it takes a keyword and it uses it to make curl requests and it parses numbers which then are stored in a mysql table. The curl request would be for example for retrieving yahoo number of results, number of diggs for that keyword, etc.So I was thinking to code it in some way to use plugins (one for yahoo, other for digg, etc).Is there any php framework that will help me in doing this?
