Serializing to JSON

VALID JSON (JavaScript Object Notation)

JSON validator – JSONLint / JSONFormatter

{"employees":[

    {"firstName":"John", "lastName":"Doe"},

    {"firstName":"Anna", "lastName":"Smith"},

    {"firstName":"Peter", "lastName":"Jones"}


]}

PURE JS CONVERSION

Polyfill for older browsers – JSON3

var JSON = JSON.stringify(OBJECT, null, 2);

PHP CONVERSION

Make sure content within the object complies to UTF-8, if not encode it before !

$JSON = json_encode($OBJECT);

Even DateTime is nicely encoded :)

class User {

    public $firstname = "";

    public $lastname  = "";

    public $birthdate = "";

}
 

$user = new User();


$user->firstname = "foo";


$user->lastname  = "bar";

 
// Returns: {"firstname":"foo","lastname":"bar"}

json_encode($user);

 

$user->birthdate = new DateTime();

 
/* Returns:
    {
        "firstname":"foo",
        "lastname":"bar",
        "birthdate": {
            "date":"2016-02-18 11:42:58",
            "timezone_type":3,
            "timezone":"Europe\/Berlin"
        }
    }
*/

json_encode($user);
