Convert PHP Object To JSON

Define a class: {code...}. The JSON format I want to generate is similar to: {code...}. The UserBean contains an uncertain number of objects... How to generate such JSON data ...? Is there anything like List & #039; & amp; lt; & #039; T & #039; & amp; gt; & #039; in JAVA .... Define a class:

class UserBean {    public $user_id = 0;    public $user_name = 'null';        function setUser_id ($user_id) {        $this->user_id = $user_id;    }    function setUser_name ($user_name) {        $this->user_name = $user_name;    }        function getUser_id () {        return $this->user_id;    }    function getUser_name () {        return $this->user_name;    }}

In this case, the JSON format to be generated is similar:

{"Info": "read the data succeed", "UserBean": [{"user_id": "21", "user_name": "James "},{": [{"user_id": "23", "user_name": "Xiaodong"}]}

Under UserBean, there are uncertain objects...

{"Info": "read the data succeed", "UserBean": [{"user_id": "21", "user_name": "James "},{": [{"user_id": "23", "user_name": "Xiaodong"}]}

PHP implementation: Convert the code into an array and encode it in json format.

$data['info'] = '';$data['UserBean'][0]['user_id'] = '';$data['UserBean'][0]['user_name'] = '';$data['UserBean'][1]['user_id'] = '';$data['UserBean'][1]['user_name'] = '';exit(json_encode($data));

You can query the UserBean result set directly from the database.
You can also assemble arrays by yourself.

Positive Solution:

$ Data ['info'] = 'sudoed'; $ data ['userbean'] [0] ['user _ id'] = '1 '; $ data ['userbean'] [0] ['user _ name'] = 'xiaoming '; $ data ['userbean'] [1] ['user _ id'] = '2 '; $ data ['userbean'] [1] ['user _ name'] = 'chestnut '; echo json_encode ($ data );
