php文件下载乱码问题
我想添加一个文件上传下载功能,由于文件可能较大,所以思路是在数据库中存储文件在服务器上的路径,下载时根据路径读取文件。最开始在上传时页面文件列表显示的中文文件名为乱码,添加了
mysql_query("SET NAMES 'utf8'");
curUser; $logger = new CategoryLogger('log_definition'); if($notice!="auto")notice($notice); $id=$mineid;//要下载文件的ID if(!isset($id) or $id=="") die("error:id none"); //定位记录,读出 $conn=mysql_connect('10.4.16.102','root','abc') or die('Unable to connect .'); mysql_select_db('greenmine',$conn) or die(mysql_error($conn)); mysql_query("SET NAMES 'utf8'"); $sql= "select * from file where id=$id"; $result= mysql_query($sql); if(!$result) die("error:mysql query"); $num=mysql_num_rows($result); if($num<1) die("error:no this recorder"); $data=mysql_result($result,0,"file_data"); //文件存储路径 $type=mysql_result($result,0,"file_type"); $name=mysql_result($result,0,"file_name"); mysql_close($conn); $file_name=$name; $file_dir=$data; if (!file_exists($file_dir)) { //检查文件是否存在 echo "文件找不到"; exit; } else { $filePath = $file_dir;//此处给出你下载的文件在服务器的什么地方 $fileName = $file_name; //此处给出你下载的文件名 $file = fopen($filePath, "r"); // 打开文件Header("Content-type:application/octet-stream ");Header("Accept-Ranges:bytes ");Header("Accept-Length: " . filesize($filePath));Header("Content-Disposition: attachment; filename= " . $fileName); // 输出文件内容 echo fread($file, filesize($filePath)); fclose($file); exit; }}?>
回复讨论(解决方案)
是文件名乱码,还是文件内容乱码?
你的库中只保存文件名,而文件是独立保存的。不是这样吗
打开文件要 $file = fopen($filePath, "r b");
供下载的文件名
Header("Content-Disposition: attachment; filename= " . $fileName);
要与用户所用操作系统配套

…… 文件名是对的,里面的内容是乱码。文件单独保存在服务器上。改成rb也不好使
只要你没有对文件内容进行操作,那么只能说文件本身就是乱码的

请问楼主,上传doc或docx这种word文件,下载后打开文件内容是否正常显示?
