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());?>
The above example will output something similar to:
Array ( [0] => Array ( [_id] => 00005b6b5361000000000000011b [name] => Bern [traits] => Array ( [0] => Friend [1] => Brother [2] => Human ) ) )
