Examples

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());?>

The above example will output something similar to:

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