[PHP] How to “Group By” with MongoDB

[Roch Delsalle]

Hi,

I would like to know if there is anyway I can "group by" my results
with MongoDB/Php.

This is the code I'm using to display my rows:

$count = $col->find(array('order_id' => array('$gt' => '0')))-
>count();
I need to group them by order_id.

Thanks for your help.

See http://www.mongodb.org/display/DOCS/Aggregation#Aggregation-Group.

I don't know the particulars for PHP but I bet you can figure it out by looking at the code.

Cheers,

Tony
