Laravel: Str::csvToArray macro

AppServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\Str;

class AppServiceProvider extends ServiceProvider
{

    public function boot()
    {
        /**
         * Turn a CSV string into a clean array.
         *
         * @param string $string
         * @return array
         */
        Str::macro('csvToArray', function ($string) {
            return array_filter(array_map('trim', str_getcsv($string)));
        });
    }
}

Here's a simple function to quickly turn a CSV string into an array. It will trim the values and filter any empty ones so you always end up with a pretty clean array without too much fuss, for example:

$string = "some, crazy, , , , mixed, bag, of , comma-separated values, , ,";

$array = Str::csvToArray($string);

// $array => ['some', 'crazy', 'mixed', 'bag', 'of', 'comma-separated values']

Ideal for occasional strings of values that are most easily separated by commas, such as .env/config/query string parameters. May not be so useful on large CSV files.
