 Porter is the all-purpose PHP data importer. She fetches data from APIs, web scraping or anywhere and serves it as an iterable [record collection](#record-collections), encouraging processing one record at a time instead of loading full data sets into memory. [Durability](#durability) features provide automatic, transparent recovery from intermittent network errors by default.
