I think the best way is to represent all the data in php with strings (true will be "true", false will be "false" and so on). The reason for this is that in php any value has a unique string representation (such as the php code itself). I post this question to speed up the design process of this program. Some values are easily converted to strings: numbers, booleans, etc. Some are not easy: objects, arrays, resources. I think the transfer object and
