    示例 #1 mysql_xdevapi\Schema::dropCollection() 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");
    $schema->dropCollection("trees");
    $schema->createCollection("buildings");

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

    以上示例的输出类似于：

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