示例

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
                )
        )
)
