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"
  }
}
