Endless loop whilst parsing mixture of control structure styles #512
Description
I can successfully reproduce an endless loop state whilst parsing our legacy codebase, which has a mixture of if/else styles.
Steps to reproduce:
- Create
test.php(with content below) composer require squizlabs/php_codesniffer(installs 2.3.0)vendor/bin/phpcs --standard=psr2 test.php
This is the file content that causes the state:
<?php foreach ($blah as $boo) : ?> <?php if ($foo): ?> <?php if ($bar) { } else { } ?> <?php endif; ?> <?php endforeach; ?>Versions
