insert with correct types to mongo

/* use this function before inserting any array to mongo */

array_walk_recursive($array,"typeCast");

/* then do insert: $mongo->$db->$collection_name->insert($array); */


/* careful with & sign before the $item, dont remove it, */

function typeCast(&$item,$key){

	if(is_numeric($item)) 	$item = (float) $item;
	else $item = (string) $item;
}

This is a good idea. This is easy to add if you have a model that supports a beforeSave() event...
