示例 #1 mysql_xdevapi\CollectionModify::__construct() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->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
)
)
)
