How to use php to download xls files. According to the source code of ECSHOP, I implemented it myself. the following examples will be used to share with you the results of viewing the source code of ECSHOP yesterday, what I have never learned is how to use php to download xls files. Based on its source code, I implemented it and successfully achieved this effect.

Source code:
The code is as follows:
/*
* @ Description: Download the xls table
*
*
*/
Function downloadXls ($ filename = ''){
$ Filename =! Empty ($ filename )? $ Filename: die ('Nothing ');

// The header is used to create a new test.xls file.
Header ("Content-Type: application/vnd. ms-excel; charset = utf8 ");
Header ("Content-Disposition: attachment; filename = $ filename ");

// The output content is directly exported to the test.xls file.
Echo 'This is the test! ';
Exit;
}

$ FileName = 'test.xls ';
DownloadXls ($ fileName );
?>

Effect:



Note: If Chinese characters are output, note the format conversion of character encoding!

But what if I want to download the xls files saved on the server?

After reading the php manual, I found that this function can be implemented very easily. I used a readfile function. The code is as follows:
The code is as follows:
/*
* @ Description: Download the xls table
*
*
*/
Function downloadXls ($ filename = ''){
$ Filename =! Empty ($ filename )? $ Filename: die ('Nothing ');

// The header is used to create a new test.xls file.
Header ("Content-Type: application/vnd. ms-excel; charset = utf8 ");
Header ("Content-Disposition: attachment; filename = $ filename ");

// Here is the file to be output
Readfile ($ filename );
}

$ FileName = 'test.xls ';
DownloadXls ($ fileName );
?>
