Hey,

i've two Eloquent Collections with the following collumns:

trackid, title, total (decimal)

and want to merge them. Each Collection has 0, one or multiple items. If a trackid is in two collections i want to add the extra total to the existing item, otherwise just add it.

Any suggestions?

You could look at PHP's array_merge or array_combine (after you have converted the results to arrays) and then convert the output to a Collection if you needed it.

Or better still, I'd probably look at running a raw DB query to get the data you wanted. It sounds to me like the standard Eloquent result sets won't cut it in this case.

If someone else has a solution to merge collections, that might be better. I've not heard of one yet though.

Hope it helps.

you could try to use merger method. http://laravel.com/api/5.1/Illuminate/Database/Eloquent/Collection.html#method_merge

$collection_one->merge($collection_two)

$collection_one->merge($collection_two)
