Question

what is the function that can be used in php json?

Answer 1

Hii @kartik,

JSON stands for JavaScript Object Notation, and is a syntax for storing and exchanging data.

Since the JSON format is a text-based format, it can easily be sent to and from a server, and used as a data format by any programming language.

PHP has some built-in functions to handle JSON.

First, we will look at the following two functions:

• json_encode()
• json_decode()

PHP - json_encode()

The json_encode() function is used to encode a value to JSON format.

Example

This example shows how to encode an associative array into a JSON object:

<?php
$age = array("Peter"=>35, "Ben"=>37, "Joe"=>43);

echo json_encode($age);
?>

PHP - json_decode()

The json_decode() function is used to decode a JSON object into a PHP object or an associative array.

Example

This example decodes JSON data into a PHP object:

<?php
$jsonobj = '{"Peter":35,"Ben":37,"Joe":43}';

var_dump(json_decode($jsonobj));
?>
