    Does anyone know of free script that takes a text string as input and gives the keywords found in that string as output?

    TIA :)

function fetch_keywords()
{
	$keywords = func_get_args();
	$text = array_shift($keywords);
	$keywords = array_map('preg_quote', $keywords);

	return preg_match_all('~(' . implode('|', $keywords) . ')~i', $text, $matches)
		? $matches[1]
		: false;
}
    PHP:
    Example:

    

$found_keywords = fetch_keywords($text, 'keyword1', 'keyword 2', 'keyword3', '...');
