Example #1 mysql_xdevapi\CollectionModify::bind() 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'])
->
arrayAppend('traits', 'Happy')
->
execute();

$result = $collection
->find()
->
execute();

print_r($result->fetchAll());
?>

Il precedente esempio visualizzerà qualcosa simile a:

Array
(
    [0] => Array
        (
            [_id] => 00005b6b53610000000000000110
            [name] => Bernie
            [traits] => Array
                (
                    [0] => Friend
                    [1] => Brother
                    [2] => Human
                    [3] => Happy
