switch statement with two variables at a time

Question

Could someone suggest the best way to have the following switch statement? I don't know that it's possible to compare two values at once, but this would be ideal:

switch($color,$size){
    case "blue","small":
        echo "blue and small";
    break;

    case "red","large";
        echo "red and large";
    break;
}

---

This could be comparable to:

if (($color == "blue") && ($size == "small")) {
    echo "blue and small";
}
elseif (($color == "red") && ($size == "large")) {
    echo "red and large";
}

---

Update I realized that I'll need to be able to negate ($color !== "blue") and compare as opposed to equating variables to strings.

Answer 1

Using the new array syntax, this looks almost like what you want:

switch ([$color, $size]) {
    case ['blue', 'small']:
        echo 'blue and small';
    break;

    case ['red', 'large'];
        echo 'red and large';
    break;
}

Answer 2

You can change the order of the comparison, but this is still not ideal.

    switch(true)
    {
      case ($color == 'blue' and $size == 'small'):
        echo "blue and small";
        break;
      case ($color == 'red' and $size == 'large'):
        echo "red and large";
        break;
      default:
        echo 'nothing';
        break;
    }
