}
fclose($out);
exit;

there is any way to call this file by jquery?

Answer 1

No you cannot do this by Javascript using jQuery or any other library, AJAX calls data in Javascript engine inside the browser.

But you can use HTML5 download attribute:

<a href="your_file.xls" download="YourFile.xls">Download Excel</a>

And give proper headers in PHP:

header("Content-Type:   application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=your_file.xls"); 
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);

EDIT:

Although the above will work, I take my words back as I found this:
