这是一个超级简单的PHP库用于将JSON文档映射成对象，类似于Java的 Jackson。
// Create a new instance of the Mapper $mapper = new \Xenolope\Cartographer\Mapper(); // Map a JSON string to a POPO // PHP 5.4 $object = $mapper->mapString( '{"name":"Liz Lemon","address":{"street":"168 Riverside Dr.","city":"New York"}}', 'Vendor\Package\Entity\Contact' ); // PHP >=5.5 $object = $mapper->mapString( '{"name":"Liz Lemon","address":{"street":"168 Riverside Dr.","city":"New York"}}', Contact::class ); // Map an already decoded (to array) JSON document to a POPO // This might happen automatically in your Request class, for example $jsonDocument = json_decode( '{"name":"Liz Lemon","address":{"street":"168 Riverside Dr.","city":"New York"}}', true ); // PHP 5.4 $object = $mapper->map($jsonDocument, 'Vendor\Package\Entity\Contact'); // PHP >= 5.5 $object = $mapper->map( '{"name":"Liz Lemon","address":{"street":"168 Riverside Dr.","city":"New York"}}', Contact::class ); 项目主页：http://www.open-open.com/lib/view/home/1419339290437
