示例 #1 mysql_xdevapi\CollectionModify::set() example

<?php
$session 
mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();

$result $collection
  
->find()

print_r($result->fetchAll());
?>

以上例程的输出类似于:

Array
(
    [0] => Array
        (
            [_id] => 00005b6b53610000000000000111
            [name] => Bern
            [traits] => Array
                (
                    [0] => Friend
                    [1] => Brother
                    [2] => Human
                )
