Ejemplo #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());
?>

El resultado del ejemplo sería algo similar a:

array(1) {
  [0]=>
  array(4) {
    ["_id"]=>
    string(28) "00005b6b536100000000000000f3"
    ["age"]=>
    int(42)
    ["job"]=>
    string(6) "Butler"
    ["name"]=>
    string(8) "Reginald"
  }
}
