Get last 12 month names from a specific month or date with Laravel - Carbon

month_names.php

<?php

use Carbon\Carbon;

//your class starts here

public function getLastTwelveMonthNames($date){
    Carbon::setlocale(config('app.locale'));
    $month_names = [
        ucfirst((new Carbon($date))->translatedFormat('F'))
    ];
    for($i=1;$i<=11;$i++){
        $month_names[$i] = ucfirst((new Carbon($date))->subMonth()->translatedFormat('F'));
        $date = (new Carbon($date))->subMonth();
    }
    return $month_names;
}

//your class ends here

 /**

     *
     * @param  int $number (of months)

     */
    public static function getLastByCount(int $number = 12): array
    {
        $months = [];
        $current = Carbon::parse(now());

        for ( $count = 0; $count < $number; $count++ ) {
            if ($count == 0 ) {
                $months = [$current->format('F')];
            } else {
                $months[] = $current->subMonth()->format('F');
            }
        }

        return $months;
    }

Returns an array (obviously I did this in Jan, so last 12 is correct at this time):
[ "January", "December", "November", "October", "September", "August", "July", "June", "May", "April", "March", "February" ]
