想问问这段代码为啥不成功

Jun 23, 2016 pm 02:28 PM

<?php	session_start();	$user = $_SESSION['login_name'];	$filename = $_GET["f"];	$file = "../upload/".$user."/".$filename;	if (file_exists($file)) {	    header('Content-Description: File Transfer');	    header('Content-Type: application/octet-stream');	    header('Content-Disposition: attachment; filename="'.basename($file).'"');	    header('Content-Transfer-Encoding: binary');	    header('Expires: 0');	    header('Cache-Control: must-revalidate');	    header('Pragma: public');	    header('Content-Length: ' . filesize($file));	    ob_clean();	    flush();	    readfile($file);	    exit;	}?>
Copy after login


在下载的时候不是弹出下载框,而是直接打印一堆乱码。(估计是readfile直接read到了屏幕上?)
谢谢!


回复讨论(解决方案)

乱码?文件是中文名?

header("Content-type: text/html; charset=GB2312");
或者
header("Content-type: text/html; charset=GBK");

贴出截图!
显然是语法错

sorry忘贴图了。
点击这里。其中我点击New Document(2).txt的那个下载链接。跳转到刚刚贴的那段代码里的php:

结果就是浏览器打开了这个txt而不是下载了这个txt。
请问为啥...

ob_clean();flush();
Copy after login
Copy after login

这两个去掉看看

ob_clean();flush();
Copy after login
Copy after login

这两个去掉看看



谢谢!最后是因为我从第二行开始写的 就报错了
看来细节马虎不得!
