create nested JSON object in php?

Question

I don't work with php much and I'm a little fuzzy on object creation. I need to make a webservice request sending json and I think I have that part covered. Before I can submit the data I need to create a nested object. I was assuming this would be trivial based on my experience with ecma based scripting languages, but I'm finding the syntax to be difficult to navigate. The object I want to create is below.

{ "client": {
    "build": "1.0",
    "name": "xxxxxx",
    "version": "1.0"
    },
    "protocolVersion": 4,
    "data": {
        "distributorId": "xxxx",
        "distributorPin": "xxxx",
        "locale": "en-US"
    }
}

I've seen a lot of examples of flat objects, but I haven't found a minimal example for a nested object yet. What would be the php syntax for the object above? Is this an unusual thing to do in php?

Answer 1

this JSON structure can be created by following PHP code

$json = json_encode(array(
     "client" => array(
        "build" => "1.0",
        "name" => "xxxxxx",
        "version" => "1.0"
     ),
     "protocolVersion" => 4,
     "data" => array(
        "distributorId" => "xxxx",
        "distributorPin" => "xxxx",
        "locale" => "en-US"
     )
));
