PHP json_encode() and json_decode() Functions

JSON (JavaScript Object Notation) stands as a universal data interchange format, recognized for its simplicity and readability. json_encode() and json_decode() in PHP allow you to seamlessly convert PHP data structures to JSON and vice versa, bridging the gap between different systems and programming languages.

Seamless Encoding with json_encode()

By utilizing the json_encode() function, you can effortlessly convert PHP arrays or objects into JSON format. This encoded JSON data can then be readily consumed by other applications, making it an invaluable tool for data sharing and integration.

Precise Decoding with json_decode()

On the flip side, the json_decode() function empowers you to convert JSON data back into PHP arrays or objects. This decoding process ensures that the retrieved data retains its original structure, allowing for seamless manipulation within your PHP application.

PHP json_encode() Function

Convert PHP arrays or objects into JSON format.


<?php 

    $array  =  array("A"=>"Broccoli", "B"=>"Tomato", "C"=>"Cucumber", "D"=>"Corn");

    echo json_encode($array);
    
    // OUTPUT : {"A":"Broccoli","B":"Tomato","C":"Cucumber","D":"Corn"}
?>

PHP json_decode() Function

Convert JSON data back into PHP arrays or objects.


<?php 

    $json  =  '{"A":"Broccoli","B":"Tomato","C":"Cucumber","D":"Corn"}';

    $result = json_decode($json);
    print_r($result);
    // OUTPUT : stdClass Object ( [A] => Broccoli [B] => Tomato [C] => Cucumber [D] => Corn )
    
    $result = json_decode($json, true);
    print_r($result);
    // OUTPUT : Array ( [A] => Broccoli [B] => Tomato [C] => Cucumber [D] => Corn )
?>

The json_encode() and json_decode() functions stand as pillars of data transformation. Their ability to seamlessly convert between PHP data structures and JSON format solidifies their role as indispensable tools for developers. By mastering the art of using json_encode() and json_decode(), you equip yourself with skills that enhance your data exchange capabilities and contribute to building interoperable web solutions.
