JsonMapper能够将嵌套的JSON结构映射成PHP类。从Web服务取得所需要的JSON数据，并将其转换成嵌套对象和数组 - 使用自己的模型类。
Map a normal object:
<?php require 'autoload.php'; $mapper = new JsonMapper(); $contactObject = $mapper->map($jsonContact, new Contact()); ?>
Map an array of objects:
<?php require 'autoload.php'; $mapper = new JsonMapper(); $contactsArray = $mapper->mapArray( $jsonContacts, new ArrayObject(), 'Contact' ); ?>
JSON from a address book web service:
{ 'name':'Sheldon Cooper', 'address': { 'street': '2311 N. Los Robles Avenue', 'city': 'Pasadena' } } Your local Contact class:
<?php class Contact { /** * Full name * @var string */ public $name; /** * @var Address */ public $address; } ?> Your local Address class:
<?php class Address { public $street; public $city; public function getGeoCoords() { //do something with the $street and $city } } ?> Your application code:
<?php $json = json_decode(file_get_contents('http://example.org/bigbang.json')); $mapper = new JsonMapper(); $contact = $mapper->map($json, new Contact()); echo "Geo coordinates for " . $contact->name . ": " . var_export($contact->address->getGeoCoords(), true); ?>
