Flickr's PHP architecture

As mentioned in the previous post, Flickr kind of rocks as a photo sharing community. Besides the taggability of photos and creation of feeds, you can even mark up photos and add notes for emphasis inside photos, tag and comment on them which is the bomb. Oh, and it has easy posting of photos to any blog service as well as creating arbitrary xml rss feeds. Quite cool.

Besides the fact it is a great little Canadian company out of Vancouver, BC they also use one of my favourite languages, PHP to get a lot of their functionality in place.

So, that being said, some interesting notes on Flickr’s architecture . I love it because it is based on all the stuff I love to use and have faith in and would choose myself if I were going to design something like this from the ground up.
