Check several field to execute switch case

Check several field to execute switch case

I have a code to check through several fields to execute certain code as
below:
switch($tag1 || $tag2 || $tag3 || $tag4 ||$tag5){
case "satay":
$imgput =
"/home/uploads/sandbox/jovine/Food/tags/satay/$img_name";
break;
case "digitalmarketing":
$imgput =
"/home/uploads/sandbox/jovine/Food/tags/interactive_marketing/$img_name";
break;
case "chillicrab":
$imgput =
"/home/uploads/sandbox/jovine/Food/tags/chilli_crab/$img_name";
break;
case "chickenrice":
$imgput =
"/home/uploads/sandbox/jovine/Food/tags/chicken_rice/$img_name";
break;
case "chendol":
$imgput =
"/home/uploads/sandbox/jovine/Food/tags/chendol/$img_name";
break;
}
But it does not work.
Anyone can help?
