Problemi con caratteri speciali in PHP

[boolbo]

In questo modo sul file addbook.php ??
if ($message != '')
{
$message = str_replace ("\n","
",$message);
$message = strip_tags ($message, '
');
$message = stripslashes($message);

o meglio sul codice:

<?php
 if ($message != '') 
 {
  $message = str_replace ("\n","
",$message);
  $message = strip_tags ($message, '
');
  $message = stripslashes($message);

  $newRow = '<div>' . ($message) .
          '
[b]' . date('d.m.Y H:i') . ' - ' . strip_tags ($name) .
          '[/b]</div><hr width="100%" size="1">';
            
  $oldRows = join ('', file (guestbook.txt') );
  $fileName = fopen ('guestbook.txt', 'w');
  fputs ($fileName, $newRow . chr(13) . chr(10) . $oldRows);
  fclose ($fileName);
 }
 
 include ("readbook.php");
?>
