JSON-PHP

JSON In PHP

A common use of JSON is to read data from a web server, and display the data in a web page.

Here how to exchange JSON data between the client and a PHP server.

The PHP File
PHP has some built-in functions to handle JSON.

Objects in PHP can be converted into JSON by using the PHP function json_encode():

Sample

// Creating an object
$myObj= new myObj("John", 30,"New York");

$myObj->name = "John";
$myObj->age = 30;
$myObj->city = "New York";

$myJSON = json_encode($myObj);

echo $myJSON;

json_decode();

$In PHP, the json_decode() function is used to decode a JSON string and convert it into a PHP variable or object. It takes a JSON string as input and returns the corresponding PHP representation.

jsonString = '{"name":"John","age":30,"city":"New York"}';

// Decoding JSON string
$data = json_decode($jsonString);

// Accessing decoded data
echo $data->name; // Output: John
echo $data->age; // Output: 30
echo $data->city; // Output: New York
