Recently, a client wanted a member search for his website that included a search by zip code. The ‘easy’ solution would be to implement the search as a LIKE statement in SQL, but the solution is inaccurate, and I like the ‘good’ solutions over the ‘easy’ ones. I looked for a CodeIgniter library that would give me the functionality for which I wanted to implement, but no such thing existed. Then, I came across Micah Carrick’s native PHP library which gave the exact functionality I was looking for. I did end up using his library, but not without modification: I’ve ported the native library to a CodeIgniter library. This is where you can get it.
