?>

However, the file doesn't show in the flexpaper.

但是,该文件不会在flexpaper中显示。

It could be that you have an extra space somewhere in your output and that this is corrupting the swf file. Check for any leading or trailing spaces in your php script (outside the php script tags).

可能是你的输出中有一个额外的空间,这会破坏swf文件。检查php脚本中的任何前导或尾随空格(在php脚本标记之外)。

You also don't need the content-disposition header in your response. I would recommend the following headers for swf files:

您还不需要在响应中使用content-disposition标头。我建议使用swf文件的以下标题:

header('Content-type: application/x-shockwave-flash'); header('Accept-Ranges: bytes'); header('Content-Length: ' . $size);

header('Content-type:application / x-shockwave-flash'); header('Accept-Ranges:bytes');标题('Content-Length:'。$ size);
