Question

Hello everyone I use MongoDB find() method like this:

$cursor = $collection->find();
foreach($cursor as $doc) {
   // do something....
}

it’s ok but my _id property is autogenereted so when I use code above $doc[_id] is Object but I need a string.

How can I convert it to string automatically. Not like this:

foreach($cursor as $doc) {      
    $doc['_id'] = (string)$doc['_id'];
}

Handling mongoid properly by json_encode used to be a bug in the php driver. It should be fixed since v1.0.11.
