Examples
Example #1 mysql_xdevapi\CollectionFind::offset() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$create = $schema->createCollection("people");
$create
->add('{"name": "Alfred", "age": 18, "job": "Butler"}')
->execute();
$create
->add('{"name": "Reginald", "age": 42, "job": "Butler"}')
->execute();
// ...
$collection = $schema->getCollection("people");
$result = $collection
->find()
->sort('age asc')
->offset(1)
->limit(1)
->execute();
var_dump($result->fetchAll());
?>
The above example will output something similar to:
array(1) { [0]=> array(4) { ["_id"]=> string(28) "00005b6b536100000000000000f3" ["age"]=> int(42) ["job"]=> string(6) "Butler" ["name"]=> string(8) "Reginald" } }
