范例

Example #1 MongoDB\BSON\Unserializable::bsonUnserialize() example

<?php

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

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

$bson = MongoDB\BSON\fromJSON('{ "foo": "bar" }');
$value = MongoDB\BSON\toPHP($bson, ['root' => 'MyDocument']);
var_dump($value);

?>

以上例程会输出：

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