Awesome! use Match Expression for simplify your code in PHP 8

PHP 8 introduces the match expression, which is a more powerful and concise alternative to the traditional switch statement.

• The traditional switch statement requires break statements and can be more verbose.
• The new match expression simplifies the syntax and returns a value directly.

for the example when we use switch case statement :

function getDayTypeWithSwitch(int $day): string
{
    switch ($day) {
        case 1:
        case 7:
            return 'weekend';
        case 2:
        case 3:
        case 4:
        case 5:
        case 6:
            return 'weekday';
        default:
            return 'unknown';
    }
}

echo getDayTypeWithSwitch(8); // Output: unknown
echo getDayTypeWithSwitch(7); // Output: weekend
echo getDayTypeWithSwitch(4); // Output: weekday

and the we comparing use match expression :

function getDayWithMatch(int $day): string
{
    return match ($day) {
        1, 7 => 'weekend',
        2, 3, 4, 5, 6 => 'weekday',
        default => 'unknown',
    };
}

echo getDayWithMatch(8); // Output: unknown
echo getDayWithMatch(7); // Output: weekend
echo getDayWithMatch(4); // Output: weekday

awesome you should be try it !

That's interesting, although I find the case statements more organized: in my opinion what's inline is more difficult to read than what's in column.
Another question though: is that only valid for single return statements? what if there is more logic involved?

Yes you're right. but for me, match expressions are better for returning simple values or expressions.

Of course, match is limited to a single expression per arm, but you can add logic using function calls or anonymous functions. for more complex logic, consider using a switch statement or separating the logic into functions.
