Example #1 Schema::existsInDatabase 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");
// ...
$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.
