Using comparison operators in a PHP 'switch' statement

Question

I have four conditions that I need to go through and I thought it would be best to use the switch statement in PHP. However, I need to check whether an integer

Answer 1

I can also confirm @bytepunk answer here is functional.

Also, expending the concept with PHP 7

switch ($interval->days)
{
    case 0:
        return '1 day';
        // break;
    case (($interval->days >= 1 && $interval->days <= 7) ?? $interval->days):
        return '1 week';
        // break;
    case (($interval->days >= 8 && $interval->days <= 31) ?? $interval->days):
        return '1 month';
        // break;
    case (($interval->days >= 31 && $interval->days <= 93) ?? $interval->days):
        return '2-3 months';
        // break;
    default:
        return '3+ months';
}

I will admit that this isn't the cleanest of code, so perhaps wrapping each case with a static-like pure function would neat things up a bit, and not forgetting to name each function (or create one generic function with parameters) to match the case. This will make it more readable.
