PHP Mongo Query NOT NULL

Anyone know the syntax for writing a php-mongo query to use NOT NULL?

I know how to do this when I query for NULL:

<?php
$cursor = $collection->find(array("someField" => null));

Is this even possible?

Yeah, you want the $ne operator, so 

$cursor = $collection->find(array("someField" => array('$ne' => null)));

Basically, the same kind of queries you would use on the Mongo console, you pass as an array to the query methods.

In your case, it could be (if you're checking that the field exists - note that the field could just be absent from the document):

array("someField" => array('$exists' => true))

Or to check if it's not equal to null:

array("someField" => array('$ne' => null))

Watch out for the $ in double quotes, since PHP will consider that a variable.
