If successful, this method produces the JSON representation of a value otherwise, it returns FALSE. In PHP, the json_encode() function is used to encode data into JSON. These function json_encode() is used to encode data into JSON and json_decode() is used to decode data from JSON, respectively. PHP has built-in functions for encoding and decoding JSON data.

The Keys in JSON are always strings, however, values can be a string, integer, true or false, null, or even an object or an array. A comma ',' is used to separate the values. An array is denoted by a left bracket ''.

Array: The array in JSON is defined as a list of values in order.

This function is used to read the file into PHP code. Each object is separated by a left curly bracket ''. Use filegetcontents() function to read JSON file into PHP.

Object: The Object in JSON is defined as a collection of key/value pairs (i.e.

JSON can be represented in the following structures: JSON, like XML, is a text-based format that is simple to write and interpret for both humans and computers but, unlike XML, JSON data structures consume less bandwidth than their XML counterparts. JSON is a lightweight data transfer format that is simple to understand and create. JSON is an abbreviation for JavaScript Object Notation. We will discuss in detail the encoding and decoding of JSON in PHP.
