插入后，我想使用json_encode()将对象传递给客户端.问题是，不包含_id值.

After doing an insert I want to pass the object to the client using json_encode(). The problem is, the _id value is not included.

$widget = array('text' => 'Some text'); $this->mongo->db->insert($widget); If I echo $widget['_id'] the string value gets displays on the screen, but I want to do something like this: $widget['widgetId'] = $widget['_id']->id; So I can do json_encode() and include the widget id: echo json_encode($widget);

推荐答案

相信这就是你所追求的.

Believe this is what you're after.

$widget['_id']->{'$id'};

类似这样的东西.

$widget = array('text' => 'Some text'); $this->mongo->db->insert($widget); $widget['widgetId'] = $widget['_id']->{'$id'}; echo json_encode($widget);
