PHP Object To JSON

In order to convert Object to JSON data, firstly you need to convert the object to an array. Finally, you need to use the json_encode() function to convert the array to JSON data. For complex Object, you need to use the custom function to do the conversion from object to an array recursively.

Example 1: Convert a simple object to an array

<?php

$object = new stdClass();
$object->name = "Bob Markina";
$object->age = 24;

$my_json = json_encode((array) $object);

print_r($my_json);
?>

Output

{
name: "Bob Markina",
age: 24
}

PHP Function to convert object to an array recursively

For complex object, you need to use this function to convert object to an array recursively.

<?php

function objectToArray($d) {
	if (is_object($d)) {
		// Gets the properties of the object
		$d = get_object_vars($d);
	}

	if (is_array($d)) {
		return array_map(__FUNCTION__, $d);
	} else {
		// Return array
		return $d;
	}
}
?>

Example 2

This is a complex object, you require to use the custom function to convert the object to array recursively.

<?php
require_one 'myfunction.php';

$employee_obj = new stdClass();
$employee_obj->name = 'Jamy Jo';
$employee_obj->age = 58;
$employee_obj->address->street = '240 Lake Rd';
$employee_obj->address->apartment = '240';
$employee_obj->address->state = 'Tx';
$employee_obj->address->city = 'Houston';
$employee_obj->address->zip = '77300';
$employee_obj->role = 'PHP Developer';

// convert to json data
$my_json = json_encode(objectToArray($employee_obj));

print_r($my_json);
?>

Output


{
name: "Jamy Jo",
age: 58,
address: {
street: "240 Lake Rd",
apartment: "240",
state: "Tx",
city: "Houston",
zip: "77300"
},
role: "PHP Developer"
}
