How to solve the problem of garbled characters in PHP download files

Solution to the garbled code when downloading files in php: First, use the ob_clean function to clear the output buffer before downloading the file; then use the flush function to refresh the output buffer; and finally download the file.

Solution:

Use the following two functions to process before downloading.

(Recommended tutorial: java course)

flush — Flush the output buffer

ob_clean — Clear (erase) the output buffer

This function is used to discard the contents of the output buffer.

This function will not destroy the output buffer, but functions like ob_end_clean() will destroy the output buffer.

Code sample:

// 文件名不要用中文//fname为要下载的文件名
    //$fpath为下载文件所在文件夹，默认是downlod
    function download($fname,$fpath="download/"){        //避免中文文件名出现检测不到文件名的情况，进行转码utf-8->gbk
        $filename=iconv('utf-8', 'gb2312', $fname);        $path=$fpath.$filename;        if(!file_exists($path)){//检测文件是否存在
            echo "文件不存在！";            die();
        }        $fp=fopen($path,'r');//只读方式打开
        $filesize=filesize($path);//文件大小

        //返回的文件(流形式)
        header("Content-type: application/octet-stream");        //按照字节大小返回
        header("Accept-Ranges: bytes");        //返回文件大小
        header("Accept-Length: $filesize");        //这里客户端的弹出对话框，对应的文件名
        header("Content-Disposition: attachment; filename=".$filename);        //================重点====================
        ob_clean();
        flush();        //=================重点===================
        //设置分流
        $buffer=1024;        //来个文件字节计数器
        $count=0;        while(!feof($fp)&&($filesize-$count>0)){            $data=fread($fp,$buffer);            $count+=$data;//计数
            echo $data;//传数据给浏览器端
        }

        fclose($fp);

    }
