    Ejemplo #1 mysql_xdevapi\Schema::createCollection() example

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

    $session->sql("DROP DATABASE IF EXISTS food")->execute();
    $session->sql("CREATE DATABASE food")->execute();
    $session->sql("CREATE TABLE food.fruit(name text, rating text)")->execute();

    $schema = $session->getSchema("food");
    $schema->createCollection("trees");

    print_r($schema->gettables());
    print_r($schema->getcollections());

    Array ( [fruit] => mysql_xdevapi\Table Object ( [name] => fruit ) ) Array ( [trees] => mysql_xdevapi\Collection Object ( [name] => trees ) )

    Ejemplo #2 mysql_xdevapi\Schema::createCollection() example

    <?php
    $collection     = $schema->createCollection("mycollection", '{
    "validation": {
    "level": "strict",
    "schema": {
    "id": "http://json-schema.org/geo",
    "description": "A geographical coordinate",
    "type": "object",
    "properties": {
    "latitude": {
    "type": "number"
    },
    "longitude": {
    "type": "number"
    }
    },
    "required": ["latitude", "longitude"]
    }
    }
    }'    );
    // Succeeds
    $collection->add('{"latitude": 10, "longitude": 20}')->execute();

    // Fails, invalid types (not numbers)
    $collection->add('{"latitude": "lat", "longitude": "long"}')->execute();
