JSON Response Format Example [PHP Code]

PHP code for JSON Response Format Example

What is JSON?

JavaScript Object Notation (JSON) is a language-neutral, text-based data interchange format that defines a few basic formatting rules for encoding structured data. The JSON format represents four primitive types (strings, numbers, booleans, and null) and two structured types (objects and arrays). A JSON file is used to exchange data between applications written in many programming languages, including Java, JavaScript, C++, C #, Go, Python, PHP, etc.

{
"Id": 78912,
"Customer": "Jason Sweet",
"Quantity": 1,
"Price": 18.00
}

Why specify the correct content type for JSON response?

Each HTTP resource has a media type, or MIME type, which describes the resource type and allows browsers and servers to understand it properly. As an example, if the server is capable of accepting both JSON and XML content types on one endpoint, a "Content-Type: application/json" will tell the server to interpret the body data as JSON, whereas a "Content-Type: application/xml" will tell the server to interpret the body data as XML.

JSON Response Format Example

To get the response format, we first need to send a request to the ReqBin echo URL:

GET /echo/get/json HTTP/1.1
Host: reqbin.com

The server returning our JSON Response Format:

HTTP/1.1 200 OK
Content-Type: application/json
Content-Length: 19

{"success":"true"}
