Example #1 Schema::existsInDatabase example

<?php
$session 
mysql_xdevapi\getSession("mysqlx://user:[email protected]");

$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");

// ...

$trees $schema->getCollection("trees");

// ...

// Is this collection still in the database (schema)?
if ($trees->existsInDatabase()) {
    echo 
"Yes, the 'trees' collection is still present.";
}

The above example will output something similar to:

Yes, the 'trees' collection is still present.
