$text = '<p>this is a link <a href="/link" class="u">a link</a> hello this is a text then a <img src="www.link.com/image.png">. then i have something like %,$,etc but i dont wanna lose my numbers and ? sign how can we do that?</p>';
$text = preg_replace('/<a.*? href="(.*?)".*?>.*?<\/a>/i', 'http://link.com$1.', $text);
$text = strip_tags($text);
$text = str_replace(array('$,','#,', '%,'), array('', ''), $text);
preg_match('/^((?:\w*?\W){0,100})/', $text, $m);
$text = $m[1];
