JSON PHP

Using json_encode with JSON_PRETTY_PRINT parameters helps to pretty print JSON and returns. We can use JSON to store and retrieve the data used in applications. It’s platform-independent and advanced interoperability in mind.

PHP is a widely used language that works with JSON and provides the json_encode() function.

What is json_encode() ?

Json_Encode() is a function in PHP that takes a data structure (array, php objects, associative array) as input and returns a JSON encoded string. It’s inbuilt function of PHP to convert PHP array, objects and generate JSON string. It also provide functionality of formatting JSON data by providing options to the json_encode().

JSON encode() is a PHP function that converts a given string to its JSON representation. This is done by converting characters to UTF-8 and wrapping them in curly braces’ ( “{” and “}”).

Syntax :

string json_encode( $value, $option, $depth )

Example : using JSON_PRETTY_PRINT option

<?php
// Declare an array 
$movie = array(
    "name"=>"Avatar ",
    "locaton"=>"Pandora",
    );

// Using json_encode() 
$json = json_encode($movie,
  JSON_PRETTY_PRINT);
print_r($json);
?>

Result

{
    "name": "Avatar ",
    "locaton": "Pandora"
}

Result without JSON_PRETTY_PRINT

{"name":"Avatar ","locaton":"Pandora"}
