$fp = fopen("tmp/$filename",'wb');
fwrite($fp, $description, strlen($description));
fclose($fp);
你好。变量 $description 包含俄语字符。写入文件后,将显示以下字符:
%u041A%u0430%u0436%u0435%u0442%u0441%u044F%u044F%u043F%u043E%u043D%u044F%u043B,%u043A%u0430%u043A%u0432%u0441%u0442%u0430%u0432%u043B%u044F%u0442% u044C %u0438%u0437%u043E%u0431%u0440%u0430%
如何解决这个问题呢?
