[franss22]

Describe the bug

SwitchDeclarationSniff throws a fatal error on some switch statements, stopping phpcbf execution.

PHP Fatal error:  Uncaught PHP_CodeSniffer\Exceptions\RuntimeException: Undefined index: scope_condition in C:\Users\franc\AppData\Roaming\Composer\vendor\squizlabs\php_codesniffer\src\Standards\PSR2\Sniffs\ControlStructures\SwitchDeclarationSniff.php on line 146 in C:\Users\franc\AppData\Roaming\Composer\vendor\squizlabs\php_codesniffer\src\Runner.php:623

Code sample

this is the switch statement that causes the error. Deleting this statement lets the formatter finish (but i obviously cant remove the switch as a fix to the formatter not working).

switch ($column->format) {
                        case "SELECTOR[MULTIPLE]":
                        case "SELECTOR[MULTIPLE][ADVANCED]":
                            $values = json_decode($value);

                            //Insertamos llos valores NxN
                            $success = Entity::selectMultipleNxN($column, //Datos de Columna a insertar
                                                                 $entity_id, //ID de la entidad principal insertada
                                                                 $values); //Valores a Insertar
                        break;
                        case 'SELECTOR[1XN][AVAILABLES]':
                        case 'SELECTOR[1XN][ONLYNEW]':

To reproduce

Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above.
2. Run phpcbf --standard=PSR12 test.php

Expected behavior

phpcbf should fix the switch statement sniff without crashing

Versions (please complete the following information)

[rodrigoprimo]

I was able to reproduce this error. Here is a simplified code snippet that causes the same problem:

switch ($value) {
    case 'one':{
        doSomething();
    }
    default:
        return 'default';
}

I haven't investigated deeply, but on a quick look, it seems that the curly brackets and the lack of return or break in the case statement are somehow tripping the tokenizer, and the T_RETURN token is missing its scope information.

I believe this may be the same issue as previously reported in squizlabs/PHP_CodeSniffer#3794, which is still open, but does contain an analysis of the underlying issues.
