示例

示例 #1 mysql_xdevapi\CollectionModify::__construct() example

sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$collection = $schema->createCollection("people");
$result = $collection
 ->add(
 '{"name": "Bernie",
 "traits": ["Friend", "Brother", "Human"]}') 
 ->execute();
$collection
 ->modify("name in ('Bernie', 'Jane')")
 ->arrayAppend('traits', 'Happy')
 ->execute();
$result = $collection
 ->find()
 ->execute();
print_r($result->fetchAll());
?>

以上示例的输出类似于：

Array
(
 [0] => Array
 (
 [_id] => 00005b6b5361000000000000010c
 [name] => Bernie
 [traits] => Array
 (
 [0] => Friend
 [1] => Brother
 [2] => Human
 [3] => Happy
 )
 )
)
