例1 MongoDB\BSON\Unserializable::bsonUnserialize example

<?php

class MyDocument implements MongoDB\BSON\Unserializable
{
    private $data = [];

    function bsonUnserialize(array $data): void
    {
        $this->data = $data;
    }
}

$bson = MongoDB\BSON\Document::fromJSON('{ "foo": "bar" }');

var_dump($bson->toPHP(['root' => 'MyDocument']));

?>

上の例の出力は以下となります。

object(MyDocument)#1 (1) {
  ["data":"MyDocument":private]=>
  array(1) {
    ["foo"]=>
    string(3) "bar"
  }
}
