Comparison of PHP dates - dd/mm/yyyy

Question

I’m looking to do a PHP date comparison of the type: if Datastart >= Datatoday + 3 days, do such a thing. Otherwise, do nothing. I tried something like this:

if ((1/86400)*(strtotime($_SESSION['buscaReserva']['dataInicio'])-strtotime(date("d/m/Y"))))>=3) {
   // Do something }
else {
   // Do nothing }

Both dates are initially in dd/mm/YYYY format. But maybe I can have today’s date in YYYY-mm-dd format. So I may have to do more than one date conversion. For example, 23/06/2015 or 2015-06-23 (today) should be at least three days less than the date of my SESSION (26/06/2015, for example).

HOW DO I DO?

Answer 1

You have to add three more days to the current date to make that comparison:

$data = $_SESSION['buscaReserva']['dataInicio'];
$hoje = date("Y-m-d");

$data = strtotime($data);
$hojeMaisTres = date('Y-m-d',strtotime($date . "+3 days"));

if ($data > $hojeMaisTres) {
    // Do something
} else {
    // Do nothing
}
