Example #1 mysql_xdevapi\CollectionModify::replace() 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 = :name")
->bind(['name' => 'Bernie'])
->replace("name", "Bern")
->execute();
$result = $collection
->find()
->execute();
print_r($result->fetchAll());
?>
Il precedente esempio visualizzerà qualcosa simile a:
Array ( [0] => Array ( [_id] => 00005b6b5361000000000000011b [name] => Bern [traits] => Array ( [0] => Friend [1] => Brother [2] => Human ) ) )
