Examples

Example #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());

The above example will output something similar to:

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

Example #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();
