PHP: properly truncating strings with “..”

Question

Currently, the method I use to truncate strings is: echo substr($message, 0, 30).\"..\";

How do I show the dots only in the case that the string has been tr

Answer 1

if (strlen($message) > 30) {
  echo substr($message, 0, 30) . "..";
} else {
  echo $message;
}
