Switch question

In some languages, you can do the following in a Switch statement...is there
a way to do this in PHP? Thanks in advance

switch($voteraction){
case '1','2','3','4','5','6','7','8','9','10':
$db_set .= "Rating = $voteraction, ";
break;
}

or do I have to the following:
switch($voteraction){
case '1':
$db_set .= "Rating = $voteraction, ";
break;
case '2':
$db_set .= "Rating = $voteraction, ";
break;
case '3':
$db_set .= "Rating = $voteraction, ";
break;
etc....
}

switch($voteraction){
case '1':
case '2':
case '3':
$db_set .= "Rating = $voteraction, ";

an alternative could be

if(in_array($voteraction,array('1','2','3','4','5' ,'6','7','8','9','10'))) {
// whatever
}
elseif(...)

another alternative could be a regular expression match but my knowledge
is very shakey in that area. Perhaps something like the following
(someone with regex knowledge would have to confirm this).

if (preg_match("/^\d.$/", $voteraction)) {
// whatever
}

If you have to do a huge number of cases, a somewhat less classy-looking
way would be (assuming voteraction is an int):

switch(true) {
case (1<=$voteraction && $voteraction<=10):
$db_set .= "Rating = $voteraction, ";
break;
...

If it's not an int, you could cast it to one first, use floor(), or whatever.

Of course, if you're doing the above, you're probably better off with
if-else blocks.

I'd use:

switch($voteraction){
case 1: case 2: case 3: case...:
$db_set .= "Rating = $voteraction, ";
break;
}
