PHP读取文件问题
我正在使用以下命令：
@header("Cache-Control: no-cache, must-revalidate");
@header("Content-Type: application/octet-stream");
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
@header("Content-Length: ".$row['file_size']);
@header("Content-Disposition: attachment; filename=\"".$row['artist'] . " - " .$row['title']."\"");
@header("Content-type: audio/mpeg;\r\n");
开始下载，现在由于某种原因它给了我
警告：readfile(http://theurl.com/downloads/the file somespaces.mp3) [function. readfile]：无法打开流：HTTP 请求失败！ HTTP/1.1 404 未找到 在 /home/belgin/public_html/dl.php 的 29
行中
，现在网址有效，我已经三重检查，但这可能是因为中有空格文件名？如果是这样我该如何解决这个问题？感谢
重述行：
readfile(http://domain.com/downloads/Warp 1.9_The Bloody Beetroots_320000.mp3)
I'm using the following :
@header("Cache-Control: no-cache, must-revalidate");
@header("Content-Type: application/octet-stream");
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
@header("Content-Length: ".$row['file_size']);
@header("Content-Disposition: attachment; filename=\"".$row['artist'] . " - " .$row['title']."\"");
@header("Content-type: audio/mpeg;\r\n");
to start a download, now for some reason its giving me
Warning: readfile(http://theurl.com/downloads/the file some spaces.mp3) [function.readfile]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
in /home/belgin/public_html/dl.php on line 29
now the url is valid, I've triple checked but could it be because there's spaces in the file name? And if so how can i fix that? Thanks
reafile line :
readfile(http://domain.com/downloads/Warp 1.9_The Bloody Beetroots_320000.mp3)

貌似url里有空格。您是否正确转义它以便在 readfile() 中使用？
It seems that the url contains spaces. Do you escape it properly for use inside readfile()?
不要对网址进行编码！它将像
http%3A%2F%2Fexample.com%2Fsome%20song.mp3进行编码。您只需要替换空格即可。所以请使用str_replace代替...readfile(str_replace(" ", "%20", $url));DO NOT encode url! It will encode like
http%3A%2F%2Fexample.com%2Fsome%20song.mp3. You just need to replace spaces. so usestr_replaceinstead...readfile(str_replace(" ", "%20", $url));urlencode() 不是正确的方法。如上所述，只需使用 str_replace() 即可。
这是为什么它不起作用的另一种可能性。这就是我的原因。有趣的是， file_exists 返回 true，但如果没有正确设置以下内容，则任何形式的向公众提供文件下载的服务都无法正常工作。
PHP 有一个名为 open_basedir 的设置，
请确保该设置与您的托管环境相关正确。 open_basedir 可以通过 php.ini 进行编辑
urlencode() is not the way to go. As mentioned above, simply use str_replace().
Just another possibility here as to why its not working. This was the cause for me. Interestingly, file_exists was returning true but no form of serving the file to the public for download was working without having the below set correctly.
PHP has a setting called open_basedir
Make sure this is set correctly relevant to your hosting environment. open_basedir can be edited via php.ini
我认为你需要 urlencode() 和 html_entities() url 或文件名或其他
I think your going to need to urlencode() and html_entities() the url or filename or whatever
