php script to get first x words of string

$string='This, is a big test. This is not a big test';

$search = array('@<script[^>]*?>.*?</script>@si',  // Strip out javascript
       '@<[\/\!]*?[^<>]*?>@si',            // Strip out HTML tags
       '@<style[^>]*?>.*?</style>@siU',    // Strip style tags properly
       '@<![\s\S]*?--[ \t\n\r]*>@'         // Strip multi-line comments including CDATA
                        );
$text = preg_replace($search, '', $string);
$words = str_word_count($text, 2);
return array_slice( $words, 0, 7);


result='This is a big test This is';

Issue
this script removes the fullstop and coma

What I want to return is 'This, is a big test. This is'
.... maintain the coma and fullstop

Can you help?
