In this tutorial you will learn how to encode and decode JSON data in PHP. What is JSON. JSON stands for JavaScript Object Notation.JSON is a standard lightweight data-interchange format which is quick and easy to parse and generate. Array and slice values encode as JSON arrays, except that []byte encodes as a base64-encoded string, and a nil slice encodes as the null JSON value. Struct values encode as JSON objects. Each exported struct field becomes a member of the object, using the field name as the object key, unless the field is omitted for one of the reasons given below.

JSON Encoder/Decoder For JavaScript. JSON(JavaScript Object Notation) is a lightweight computer data interchange format. It is a text-based, semi-readable format for representing simple data structures and associative arrays. Creates a new JSON::XS object that can be used to de/encode JSON strings. All boolean flags described below are by default disabled (with the exception of allow_nonref, which defaults to enabled since version 4.0). The mutators for flags all return the JSON object again and thus calls can be chained:
