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 );
