Question

I have a quick question, what is the fast way to grab and delete an object from a mongo collection. Here is the code, I have currently:

$cursor = $coll->find(         


        

Answer 1

Use the findAndRemove function as documented here: http://api.mongodb.org/java/current/com/mongodb/DBCollection.html

The findAndRemove function retrieve and object from the mongo database and delete it in a single (atomic) operation.

findAndRemove(query, sort[, options], callback)

• The query object is used to retrieve the object from the database (see collection.find())
• The sort parameter is used to sort the results (in case many where found)
