date_diff

By
Para comparar fechas en php, se utiliza el siguiente metodo: date_diff($fecha1,$fecha2);

yo lo probé asi:

    $fechapp1=  date_create_from_format('d-m-Y', '03-08-2012');
    $fechapp2=  date_create_from_format('d-m-Y', '08-08-2012');
    echo date_format($fechapp1, 'd-m-y')."...";
    echo date_format($fechapp2, 'd-m-y').",,,";
    $diferencia= date_diff($fechapp1, $fechapp2);
    echo $diferencia->format('%R%a dias');

y debe salir algo asi:

03-08-2012...08-08-2012,,,+5 dias

ahi se ve la diferencia de dias entre las dos fechas.

 cualquier duda, comentar y les responderé

I thought that when you set the margins on ITextSharp document, you set also the margin for the header. but then I realized the margins are just the margins, and there is no headers by default on ITextSharp. In order to add a header in ITextSharp, you have to use PageEvent. And implement the class HeaderFooterFDA2, you can rename that class. To avoid header overlaps your content, when there are a lot of content that break on a new page. You have to set an additional margin on the method WriteSelectedRows(), in my case I added + 70 units. I hope It helps you.
