这是我的PHP代码:
switch ($i) {
case 0:
echo '$i is 0.';
break;
case 1:
case 2:
case 3:
case 4:
case 5:
echo '$i is somewhere between 1 and 5.';
break;
case 6:
case 7:
echo '$i is either 6 or 7.';
default:
echo "I don't know how much \$i is.";
}
?>
现在,我如何使用替代语法而不是大括号语法来制作代码?

在这种情况下,我甚至不觉得有使用Switch的要求,最好使用if或if else语句。
if($i==0){
echo "value is 0";
} else if($i>0 && $i<6){
echo "value is between 1 and 5";
}else if($i>5 && $i<8){
echo "value is 6 or 7";
}else{
echo "unknown value";
}

如果您想在此示例中使用替代语法,则问题的实际答案是:
switch ($i):
case 0:
echo '$i is 0.';
break;
case 1:
case 2:
case 3:
case 4:
case 5:
echo '$i is somewhere between 1 and 5.';
break;
case 6:
case 7:
echo '$i is either 6 or 7.';
default:
echo "I don't know how much \$i is.";
endswitch;
?>
