说明
abstract public MongoDB\BSON\Unserializable::bsonUnserialize

范例
Example #1 MongoDB\BSON\Unserializable::bsonUnserialize() example
<?phpclass 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"
}
}
