PHP - Select Case / Switch help (looking for a good example)

I spent some time searching for a good php select case / switch example, but the one I found doesn't seem to work... Maybe I can get a better example since it's about 20 or so cases total, and I don't want to do that on if/elses :) I've taken out other things inside of them for sanity.

PHP Code:


		
			
switch ($magic) {



case 0 to $chance_for_normal:

$special = 0;

break;

case $endchance to 20: //must be set lower if normal chance is reduced.

$special = 1;

break;



case 21 to 25:

$special = 3;

break;



etc.....



etc.....

Seems to just give me errors. Am I doing it wrong?

If you have trouble with php code look for an example within vBulletin or other scripts, here is an example of a proper switch statement, you can find it in memberlist.php in vBulletin 3.0.3

PHP Code:


		
			
    switch ($sortfield)

    {

        case 'username':

            $sqlsort = 'user.username';

            break;

        case 'joindate':

            $sqlsort = 'user.joindate';

            break;

        case 'posts':

            $sqlsort = 'user.posts';

            break;

        case 'lastvisit':

            $sqlsort = 'lastvisittime';

            break;

        case 'reputation':

            $sqlsort = iif($show['reputationcol'], 'reputationscore', 'user.username');

            $secondarysortsql = ', user.username';

            break;

        default:

            $sqlsort = 'user.username';

            $sortfield = 'username';

    }

Is that clear enough? :)

Well, it doesn't use "to"s, or numbers, but I suppose I can try again. I did look at the memberlist one before :)

UPDATE :

For future refrence or similar questions, it's like this...

PHP Code:


		
			
case '0 to $chance':

PHP Code:


		
			
case '0 to 5':

Generaly text has to be in quotes, but numbers don't.

The only way to do what you wanna do without having heaps of code is to do the following:

PHP Code:


		
			
switch ($magic) {

    case 1:

    case 2:

    case 3:

    ...

    case 18:

    case 19:

    case 20:

        $special = 1;

        break;

    case 21:

    case 22:

    case 23:

    case 24:

    case 25:

        $special = 3;

        break;

    default:

        $special = 0;

}

The logic of it is that if if comes to case 15, and doesn't come to a break before the end of case 20 then it will apply the $special = 1 for all cases up to 20 - you will have to enter each case but not define the value for each one.

}

I updated my post with a method that worked...

PHP Code:


		
			
case '0 to $chance':

PHP Code:


		
			
case '0 to 5':
