I love what blockchain.info is doing, it seems like a really great service. I'd like to make my own, at least generally along those lines, probably just for my own gits and shiggles. Entirely PHP, entirely FOSS, simple and clean.
How on Earth do I go about getting and parsing the blockchain without using a wallet? Preferably all in PHP? Any ideas? Once retrieved and turned into discrete transactions, I'd like to stuff the whole thing into a sql database, and after that point it's really pretty simple to manhandle the data however it wants to be. But getting to the point of the entire transaction history in a db...I'm stumped.
