How to decode and encode JSON in PHP
How to decode and encode JSON in PHP
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.
There are two functions for decode and encode the JSON in PHP, as follows
- json_encode()
- json_decode()
json_encode()
The json_encode() function is used to encode a value to JSON format.
<?php
$age = array("Peter"=>35, "Ben"=>37, "Joe"=>43);
echo json_encode($age);
?>
<?php$cars = array("Volvo", "BMW", "Toyota");
echo json_encode($cars);?>
<?php
$cars = array("Volvo", "BMW", "Toyota");
echo json_encode($cars);
?>
json_decode()
The json_decode() function is used to decode a JSON object into a PHP object or an associative array.
<?php
$jsonobj = '{"Peter":35,"Ben":37,"Joe":43}';
var_dump(json_decode($jsonobj));
?>
The json_decode() function returns an object by default. The json_decode() function has a second parameter, and when set to true, JSON objects are decoded into associative arrays.
Accessing the Decoded Values
<?php
$jsonobj = '{"Peter":35,"Ben":37,"Joe":43}';
$obj = json_decode($jsonobj);
echo $obj->Peter;
echo $obj->Ben;
echo $obj->Joe;
?>
