php-switch语句一次有两个变量

有人建议最好的方法来进行以下switch语句？我不知道可以一次比较两个值,但这是理想的：

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

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

这可以相当于：

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

更新
我意识到我需要能够否定($color！==“blue”),而不是将变量等同于字符串.

你可以改变比较的顺序,但这还不是很理想.

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;
    }
