<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");

$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$result_sql = $session->sql("CREATE DATABASE addressbook")->execute();

var_dump($result_sql);


$schema     = $session->getSchema("addressbook");
$collection = $schema->createCollection("humans");

$result_collection = $collection->add(
  '{"name": "Jane",
    "jobs": [{"title":"Scientist","Salary":18000}, {"title":"Mother","Salary":0}],
    "hobbies": ["Walking","Making pies"]}');

var_dump($result_collection);
var_dump($result_collection_executed);
?>
