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;
}
