Hi,

bin/phpcbf --version
PHP_CodeSniffer version 2.5.1 (stable) by Squiz (http://www.squiz.net)

I tried to clean the following function:

bin/phpcbf --standard=PSR2 test.php

<?php // test.php function sth($data, $type) { switch ($type) { case Format::NONE: return true; case Format::DATE: case Format::TIME: case Format::DATETIME: case Format::DATETIMEU: if (empty($data)) { return true; } elseif (!is_object($data)) { $datetime = date_create($data); return ($datetime!==false); } elseif ($data instanceof \DateTime) return true; else { throw new FormatException('Unknown datetime object: ' . get_class($data)); } break; default: throw new FormatException('Unknown format: ' . print_r($type, true)); } }

This results in:

Processing test.php [PHP => 199 tokens in 26 lines]... DONE in 8ms (12 fixable violations)
=> Fixing file: 0/12 violations remaining [made 6 passes]... DONE in 51ms
Patched 1 file
Time: 134ms; Memory: 4.75Mb

➜ /tmp php -l test.php
PHP Parse error: syntax error, unexpected 'else' (T_ELSE) in test.php on line 20
Errors parsing test.php

I did the same with

PHP_CodeSniffer version 2.3.4 (stable) by Squiz (http://www.squiz.net)

=> this does not create a parse error.
