substitute break outside of a loop by return false (#114)

* substitute break outside of a loop by `return false`

PHP 7 doesn't accept `break` statements outside of loop or switch structures and
returns an error. See https://www.php.net/manual/en/control-structures.break.php
I substituted the `break` by a `return false` which as far as I assume does the same.

* Update the version number

* Update the changelog with version 1.37.4
