php一段代碼，處理文件下載時的文件名，后來客戶反饋說firefox，safari下的中文文件名不能正常顯示。

        $file_info['title'] = rawurlencode($file_info['title']);
        $filename=iconv('utf-8', 'gbk', $file_info['title']);
        header("Content-Disposition:attachment;filename = " . $filename);

修正為以下內容后firefox,safari下正常顯示

如果沒有興趣請看簡版，一句話解決
if (preg_match("/Safari/", $ua)) { 
header( 'Content-Disposition: attachment; filename*="UTF-8\'\'' .  rawurlencode($file_info['title']) );
}

之前試過和firefox一樣處理方法，結果下載的文件名連擴展名都沒有了
 header( 'Content-Disposition: attachment; filename*=UTF-8\'\'' .  rawurlencode($file_info['title'])  . '"' ); 

兜兜轉轉后發現去掉一對雙引號就可以，

求此時此刻內心的陰影面積

一堆代碼參考一下。


       $filename = "中文 文件名.txt";

//        header("Content-Disposition:attachment;filename = " . $filename);


        $encoded_filename =  $file_info['title'] 
        $ua = $_SERVER["HTTP_USER_AGENT"];
        //IE
        if(preg_match("/MSIE/", $ua) || preg_match("/Trident\/7.0/", $ua)){
            header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');
        } else if (preg_match("/Firefox/", $ua)) {
            header('Content-Disposition: attachment; filename*="utf8\'\'' . $filename . '"');
        } else if (preg_match("/Safari/", $ua)) {
            header( 'Content-Disposition: attachment; filename*=UTF-8\'\'' . $encoded_filename );
        } else {
            header('Content-Disposition: attachment; filename="' . $filename . '"');
        }
