How to get all _ids from MongoDB collection in PHP? -

-

i want _ids mongodb collection using php. possible?

yes, is:

$connection = new mongoclient(); $collection = $connection->database->collectionname;  $cursor = $collection->find(); foreach ( $cursor $id => $value ) {     var_dump($value['_id']); //object(mongoid) }

you can read more mongoid object here

from comments:

if need actual id string, , try usual way, php whine because starts dollar sign , thinks it's variable. instead, use notation:

$mongoid->{'$id'} //get $id property of mongoid object
