Switch case with fallthrough?

Question

I am looking for the correct syntax of the switch statement with fallthrough cases in Bash (ideally case-insensitive). In PHP I would program it like:

switch

If the values are integer then you can use [2-3] or you can use [5,7,8] for non continuous values.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    1)
        echo "one"
        ;;
    [2-3])
        echo "two or three"
        ;;
    [4-6])
        echo "four to six"
        ;;
    [7,9])
        echo "seven or nine"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done

If the values are string then you can use |.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    "one")
        echo "one"
        ;;
    "two" | "three")
        echo "two or three"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done
