You could get the regex to do the search and the extraction in one go:
$MyOriginalString = "This is my original string.\nWhat do you think
about this script?";
$MaxWords = 6; // How many words are needed?
$matches = array();
if (preg_match("/(\b\w+\b\W*){1,$MaxWords}/", $MyOriginalString,
$matches)) {
$result = trim($matches[0]);
echo $result;
}
