如何让php切换案例检查类型？

Question

我希望切换案例与===而不是==进行核对。

<?php
$favcolor = "1";

switch ($favcolor) {
    case 1:
        echo "Your favorite color is red!";
        break;
    case "blue":
        echo "Your favorite color is blue!";
        break;
    case "1":
        echo "Your favorite color is green!";
        break;
    default:
        echo "Your favorite color is neither red, blue, nor green!";
}
?>

这给了我：

Your favorite color is red! 

但我希望它说绿色。怎么可能？

请注意，开关/外壳的比较松散。

使用开关无法实现此目的，请考虑使用if - elseif - else，例如：

if ( $favcolor === 1 )
    echo "Your favorite color is red!";
elseif ( $favcolor === "blue" )
    echo "Your favorite color is blue!";
elseif ( $favcolor === "1" )
    echo "Your favorite color is green!";
else
    echo "Your favorite color is neither red, blue, nor green!";
