PHP has this really neat function, json_encode(). It can take an object of whatever type, including my own class with child arrays/classes, and make a valid JSON string out of it. I was going to write this function myself but I found PHP already has it.
There’s one concern I have about it – it takes the entire object tree and makes json out of it, and all my member variable names end up as keys in the JSON. So without much difficulty you can look at the JSON and see exactly how I structure the data on the server in the PHP.
I’m not sure I really care but this makes me uneasy. It just doesn’t feel right. Maybe it will be ok.
