Example 5.35 mysql_xdevapi\CollectionFind::limit
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"); $create = $schema->createCollection("people"); $create ->add('{"name": "Alfred", "age": 18, "job": "Butler"}') ->execute(); $create ->add('{"name": "Reginald", "age": 42, "job": "Butler"}') ->execute(); // ... $collection = $schema->getCollection("people"); $result = $collection ->find('job like :job and age > :age') ->bind(['job' => 'Butler', 'age' => 16]) ->sort('age desc') ->limit(1) ->execute(); var_dump($result->fetchAll()); ?>
The above example will output something similar to:
array(1) { [0]=> array(4) { ["_id"]=> string(28) "00005b6b536100000000000000f3" ["age"]=> int(42) ["job"]=> string(6) "Butler" ["name"]=> string(8) "Reginald" } }
