}

mongodb geo query sample

Please make sure you typecast the lat-longs with float. Or else mongo extension will treat it as a string (surprise, surprise) and query will return assuming empty condition (this took forever me to find).

EDIT: Have a look at Cakephp mongo driver source for more ways to use geo queries.https://github.com/ichikaway/cakephp-mongodb/blob/master/samples/controllers/geos_controller.php
