PHP: crop text at word boundaries

Question

Someone has the exact name of the function that Drupal uses to flip the following line:

"Hello, how are you. Another text."

in

    if (count($string) > $words)
    {
        return implode(' ', array_slice($string, 0, $words)) . '...';
    }

    return implode(' ', $string);
}
