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

[Tekton]

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': 


or

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': 


or

PHP Code:

case '0 to 5':
