PHP代码:


// write to tmp file, then rename it to avoid

 // file locking race condition

    $_tmp_file = tempnam($_dirname, \\'wrt\\');

    if (!($fd = @fopen($_tmp_file, \\'wb\\'))) {

        $_tmp_file = $_dirname . DIRECTORY_SEPARATOR . uniqid(\\'wrt\\');

        if (!($fd = @fopen($_tmp_file, \\'wb\\'))) {

            $smarty->trigger_error("problem writing temporary file \\'$_tmp_file\\'");

            return false;

        }

    }

   fwrite($fd, $params[\\'contents\\']);

   fclose($fd);
