Try reading the error message; an alternative is mentioned there.

I have read it but I don't know how to modify it

$comment = preg_replace_callback('~\b(\w)(\w+)~e', '"$1".strtolower("$2")', $comment);

preg_replace_callback(): Requires argument 2, '"$1".strtolower("$2")', to be a valid callback in

$comment = preg_replace_callback(
  '~\b(\w)(\w+)~'        // no more "e" modifier
  function($matches) {   // can use an in-line anonymous function
    return($matches[1].strtolower($matches[2]));
  },
  $comment
);

thank you but it this produces an error:

unexpected 'function' (T_FUNCTION), expecting ',' or '

Looks like I left out a comma after the regex string.
