是否可以执行两种情况的交换机？

I have something like this

switch($m){
    case 1:
        some code
        break;
    case 2:
        some code
        break;
    case 3:
        some code
        break;
}

I need that then case 2 executes it will go back and execute case 1. or then case 3 executes i need it to go back and execute case 1.

Is it possible to do? Thank you!

If I understood correctly, something like this should work for you:

function duck($m)
{
  switch($m){
      case 1:
          //some code
          break;
      case 2:
          duck(1);
          break;
      case 3:
          duck(1);
          break;
  }
}


duck(2);

Good luck!

It is possible if you set it up right:

switch($var){
    case 1:
        some code 1;
    case 2:
        some code 2;
        break;
    case 3:
        some code 3;
    default
        some code 4;
        break;
}

Basically, it will keep going down the flow of the switch til it reaches a break. So, in this example, case 2 will execute code 2, but case one will execute first code 1 THEN code 2, because there is no break. Same thing for case 3 and default: case 3 would hit both some code 3 and some code 4.
