The MongoMinKey class

INTRODUCTION
       MongoMinKey is an special type used by the database that compares less than all other possible BSON values. Thus, if a query is sorted by a
       given field in ascending order, any document with a MongoMinKey as its value will be returned first.

       MongoMinKey has no associated fields, methods, or constants. It is merely the "smallest" value that can be represented in the database.

       Note

	      MongoMinKey is used internally by MongoDB for indexing and sharding. There is generally no reason to use this class in  an  applica-
	      tion.

CLASS SYNOPSIS
       MongoMinKey

       MongoMinKey

USING  MongoMinKey"; AS A VALUE"
       <?php

       $collection->insert(array("task" => "lunch", "doBy" => new MongoMinKey));
       $collection->insert(array("task" => "staff meeting", "doBy" => new MongoDate(strtotime("+4 days"))));

       $cursor = $collection->find()->sort(array("doBy" => 1));

       ?>

	The  cursor  will  return  the	lunch  document  followed by the staff meeting document. The lunch document will always be returned first,
       regardless of what else is added to the collection (unless other documents are added with MongoMinKey in their "doBy" field).  See Also
