Laravel Collection Public API: sortByDesc

sortByDesc($callback, $options = SORT_REGULAR)

The sortByDesc method operates exactly the same as the sortBy method. The only differences is that the sortByDesc method does not define a $descending parameter. The sortByDesc method internally makes a call to the sortBy method passing true as the argument for the $descending parameter.

The following calls to the sortBy and sortByDesc methods are functionally equivalent:

{lang="php",line-numbers=on}

 1<?php
 2 
 3use Illuminate\Support\Collection;
 4 
 5// Create a new collection instance.
 6$collection = new Collection([
 7    ['name' => 'Marshall']
 8]);
 9 
10$sorted = $collection->sortBy('name', SORT_REGULAR, true);
11 
12$sorted = $collection->sortByDesc('name', SORT_REGULAR);
13 
14$sorted = $collection->sortByDesc('name');
