How to handle a PHP switch with different types?

Question

How can I make the switch respect data types ( is there a workaround better then if/else ) ?

$value = false; // should echo false

$value = null; // should ec

another option, depending on what you like to look at:

switch($foo ?: strtoupper(gettype($foo))){
    case 'bar':
    case 'bork':
        echo $foo;
        break;

    case 'NULL': // $foo === null
        echo 'null';
        break;

    case 'INTEGER': // $foo === 0
        echo 'zero';
        break;

    case 'ARRAY': // $foo === array()
        echo 'array';
        break;

    case 'STRING': // $foo === ''
        echo 'empty';
        break;

    case 'BOOLEAN': // $foo === false
        echo 'false';
        break;

    default:
        echo $foo;
        break;
}

depending on your data, you could include an underscore for added clarity, like '_NULL', but it's not as clean IMO.

personally, I concur with the accepted answer for something like a quick null check:

case $foo === null:
