Do many here use the SPL library?
I use the ArrayAccess interface all the time. It allows me to get some OOP benefits for data structures while still having the ease of use of an array.
For example, we opened up a SOAP interface for our system. Internally we had things working as arrays but in order to provider more structure for the web service, we needed to have objects. Instead of rewriting the whole code base, I just made a few new classes which implemented ArrayAccess, changed $thing = array(); to $thing = new ArrayLikeObject(); and left the rest of the code alone. The rest of the code still does things like $thing[$key] = $var; but the SOAP interface has the objects it needs. It saved us from a lot of extra work rewriting tons of code.
