Header ("Cache-control:public"); Header (' Content-type:application/vnd.ms-excel '); Header ("content-disposition:attachment; Filename=report.xls "); Copy Code If you don't add the first sentence, it pops up: Internet Explorer cannot download **.php (from * * website). Internet Explorer cannot open the Internet site. The requested Web site is not available, or cannot be found, please try again later. And even the name is not the name of the set: Report.xls, but **.php, the first sentence to add on it.
