Refactoring to collection filter Collections are very powerful, this refactor shows the filter method https://laravel.com/docs/8.x/collections#method-filter
requires: laravel 5.1

The filter method filters the collection using the given callback, keeping only those items that pass a given truth test:

Original code



        $arr = array(
            1, 2, 99, 201,
        );

        $between1and100 = array_filter($arr, function ($value) {
            return ($value >= 1 && $value <= 100);
        });

        

Refactored code



        $arr = array(
            1, 2, 99, 201,
        );

        $between1and100 = collect($arr)->filter(fn($value) => ($value >= 1 && $value <= 100));

        

Here is the output of the code

This is the output of original
