jump from one "case" to another?

[Hyaku_]

Hi!
is this posible?
[code]switch($var){
    case 1:
        if($something == $something_else){
                  jump_to_case_2;
        }
    break;

    case 2:
              ......
    break;

}[/code]
Thanks!

Nope. What are you trying to do exactly?

[btherl]

It's not possible.. but you can do this:

[code=php:0]switch($var) {
case 1:
  if ($something != $something_else) {
    break;
  }
case 2:
    .....
break;
}[/code]


That will fall through to case 2 if $something == $something_else.

[trq]

case 2 still will not run unless $var == 2.

That's not true.

Try this example:
[code]<?php
if (isset($_GET['v']))
switch($_GET['v']) {
case '0':
echo 'zero<br>';
case '1':
echo 'one<br>';
case '2':
echo 'two<br>';
case '3':
echo 'three<br>';
default:
echo 'default<br>';
}
?>[/code]

Or in action at http://www.rbnsn.com/phpfreaks/case_test.php?v=0

Well, this doesn't work?

[code]#!/usr/bin/php
<?php

    $a = 10;
    $v = 1;

    switch ($v) {
        case 1:
            if ($a == 10) {
                break;
            } 
        break;
        case 2:
            echo "this is two";
        break;
    } 

?>
[/code]

[kenrbnsn]

Leave out the 2nd "break" in "case 1:".

Still doesn't work.

[kenrbnsn]

It's not displaying anything since $a is 10 in your example, change it to something else:
[code]<?php
    $a = 20;
    $v = 1;

    switch ($v) {
        case 1:
            if ($a == 10) {
                break;
            } 
        case 2:
            echo "this is two";
        break;
    } 

?>[/code]

Yeah, Im aware of that, but read the question.

[Hyaku_]

Well, I was trying to acomplish this:
[code]

switch($mode){
      case "read_pm":
                  if(id_of_pm_doesn't_exist_in_the_db){
                            don't_display_error_just_jump_to_case_list_pm;
                  }
      break;

    case "list_pm":
              list_all_private_messages();
    break;

}[/code]
I know how it can be done in different way, but I just thought if it would be posible to go to case "list_pm" on error, it would be preatty clean, but I guess I could use [i]goto[/i], but I don't want to use it.. Thanks!

[trq]

There is no such thing as goto in php [i]yet[/i].

[Hyaku_]

I didn't know that! Thanks!  :-X
