问我想创建一个在文件名中包含特殊字符的下载函数

EN

function download(){
            $filename = "google _(){}[]valentine~!@#$%^&*()_+`1=-.flv";
            $filepath = "uploads/" . $filename;
            header("Pragma: public");
            header("Expires: 0");
            header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
            //setting content type of page
            header("Content-Type: application/force-download");
            header("Content-Disposition: attachment; filename=" . $filename);
            header("Content-Description: File Transfer");
            //Read File it will start downloading
            readfile($filepath);
}
