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.
