//Hi, this is actually possible already in PHP already, and doesn't need any extra functionality.

// You can specify a function to be called to combine multiple arguments into a single
// value inside case statements like this:


function f($value, $access = null) {
    $knownAccessTypes = [
        'read-only',
        'read-write'
    ];
    
    if (in_array($access, $knownAccessTypes)) {
        return $value.$access;
    }

    return $value;
}

function multiSwitchFunction($value, $access = null) {

    switch (f($value, $access)) {
        case f('a', 'read-only'):       return 'a r';
        case f('a', 'read-write'):      return 'a w';
        case f('a'):                    return 'a default';

        case f('b', 'read-only'):       return 'b r';
        case f('b', 'read-write'):      return 'b w ';

        case f('c', 'read-only'):       return 'c r';
        case f('c', 'read-write'):      return 'c w';

        case f('d', 'read-only'):       return 'd r';
        case f('d', 'read-write'):      return 'd w' ;

        default:                        return "unknown";
    }
}

var_dump(multiSwitchFunction('a', 'read-write'));
var_dump(multiSwitchFunction('a', 'foobar'));
var_dump(multiSwitchFunction('d', 'read-write'));
var_dump(multiSwitchFunction('d', 'foobar'));
