Example #1 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"
  }
}
