When exporting excel files in phpexcel, you cannot download files using IE8. saving the file as a dialog box flashed through

When exporting excel files in phpexcel, you cannot download the files using IE8. when you save the files as a dialog box, the IE 6 ie7 ie9 chrome ff is normal, that is, ie8 is unavailable, after clicking the export button, the "save" dialog box pops up and closes instantly. no solution was found after I checked it online.
You can see a solution in phpexcel:
If (strpos ($ _ SERVER ['http _ USER_AGENT '], 'msi ')){
Session_cache_limiter ("public ");
}
Session_start ();

The combination of various headers fails, so I have to seek help here and hope it can be solved.

Supplement: I don't know if it is related to window. open ().

There are not many points in total. I hope you can find a solution to this post.

I tested it. the values of $ _ POST [] in IE8 are all null. it should be caused by this problem, that is, when a new page is automatically displayed during download, what should I do if the session value is not passed in?

No code ......

It seems to be a problem with the 360 browser. this problem may occur in the IE8 kernel mode of 360, and no solution has been found yet.

How does the save dialog box pop up? I don't know how to set the save as dialog box?
