Rafael Dohms has posted the first part of a series he's writing looking at the Iterators that come with the Standard PHP Library (SPL). In this first article he focuses on Directory iterators.
Wouldnâ€™t it be nice if you could go by life just applying a foreach to each year and life day by day? Ok, that was an awful joke, but using iterators does make life a lot easier and fun, and thatâ€™s without mentioning cleaner code. SPLâ€™s iterator classes are really awesome and helpful, replacing multiple lines of code and a handful functions with a simple new this and a foreach can really help cleaning up code.
