本文介绍了一次带有两个变量的 switch 语句的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
有人可以建议使用以下 switch 语句的最佳方法吗?我不知道是否可以同时比较两个值，但这是理想的:
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;
}
这可以与以下内容相媲美:
This could be comparable to:
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 ($color !== "blue") 并进行比较，而不是将变量等同于字符串.
Update
I realized that I'll need to be able to negate ($color !== "blue") and compare as opposed to equating variables to strings.
推荐答案
你可以改变比较的顺序，但这仍然不理想.
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;
}
