This is probably quicker using a callback function like this:
$string = "<!-- a\nlong\rtest\n\rstring -->";
echo nl2br(htmlentities($string));
echo '<br>';
function replace($str){
return preg_replace('/\n\r|\n|\r/',' ',$str[0]);
}
$newstring = preg_replace_callback('/<!--(.*?)-->/s','replace',$string);
echo nl2br(htmlentities($newstring));
