    require 'class/fileDown.class.php';
    $name=urldecode($_REQUEST["name"]);
    //echo $name;
    down_file($name,"/MianXiangDuixiang/down/");

fileDown.class.php页面如下:

    function down_file($file_name,$file_sub_dir)
    {
        $file_name=iconv("gb2312","GBK",$file_name);
        $file_path = $_SERVER['DOCUMENT_ROOT'].$file_sub_dir.$file_name;
        if(!file_exists($file_path))
        {
            echo"文件不存在";
            return ;
        }
        $fp = fopen($file_path,"r");
        $file_size = filesize($file_path);
        header("Content-type: application/octet-stream");
        header("Accept-Ranges: bytes");
        header("Accept-Length: $file_size");
        header("Content-Disposition: attachment; filename=".$file_name);
        $buffer = 1024;
        $file_count = 0;
        while(!feof($fp) && ($file_size-$file_count>0))
        {
            $file_data = fread($fp,$buffer);
            $file_count+=$buffer;
            echo $file_data;
        }
        fclose($fp);
    }
