PHP Excel page breaks

[kesz1]

Hello;
I generate a basic excel report from a php page (updating the header content) and I need to dynamically add page breaks to this excel file. I tried:
<DIV style="page-break-after:always"></DIV>
which works fine if the output page was for the browser, but, when I change the I update the header to display as excel, the breaks do not work.

Does anyone have any suggestions or examples to add page breaks to the php script that the excel file will recognize?

Thanks
