php
<?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");

// Yields a DocResult object
$result = $collection
  ->find('job like :job and age > :age')
  ->bind(['job' => 'Butler', 'age' => 16])
  ->sort('age desc')
  ->execute();

if (!$result->getWarningsCount()) {
    echo "There was an error:\n";
    print_r($result->getWarnings());
    exit;
}

var_dump($result->fetchOne());
?>
