    }
}

Your question title suggests that you are under the assumption that, using PHP, you can save an Excel file on the client's PC. Not exactly. You can save it to your local webserver (as you've already found out). But to transfer that to the client PC, you should offer it up as a download.

Once the file is done being written (as you are already doing), present the user with a link to the file on your server. They will then be able to choose where it should be downloaded on their PC.

Another possibility would be to write out the excel file data as the HTTP response and set the Content-Type header to something like application/vnd.ms-excel (or whatever is correct for your file type) and a Content-Disposition of attachment (example).

I'm not familiar with ExcelWriter, so I don't know if it has some kind of a dump function or not. Perhaps after you write out the file you just do something like this:

header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename=company'. $id .'.xls');

echo file_get_contents('./excel/company'. $id .'.xls');
"./excel/company".$id.".xls"

Is a relative path are you sure this is where you want to save it? You can use $_SERVER['DOCUMENT_ROOT'] to get the doc root and use that + the path like this.

$_SERVER['DOCUMENT_ROOT'] . "/excel/company".$id.".xls

also don't forget to close the file as well.

$excel->close();

the solution is in their documentation

excerpt from the above site

// sending HTTP headers
$workbook->send('test.xls'); 

What that means is that we are sending our spreadsheet to a browser. But what if we just want to save the spreadsheet in our machine? Well, you just have to omit that line and give a valid file path to the workbook constructor.

For example, if we wanted to save the same spreadsheet we created in our first example to a file named 'test.xls', we would do it like so:

you could then point the user to a link to that file so that he can save it where he likes
