#Laravel check no results from eloquent find code#
I highly recommend you check out the source code for the Collection class, it's pretty simple. If you're not sure what class you're actually working with, try doing var_dump(User::all()) and experimenting to see what classes it's actually returning (with help of get_class(.)). Those methods also exist on the Collection object, which can get returned from the Query Builder if there are multiple results. result->count () // Return count of records in result.
result->isEmpty () // True if result is empty. when you call certain methods like ->all() ->first() ->lists() and others).
