Return to previous page and refresh it in php?

Question

I have a submit form and while submitting the form it will load a php for the process like insert to DB and all.For going back to the submit form I added

 header("location:javascript://history.go(-1)");

But how to reload the page (the submit form page so user can see the submitted form details)

Answer 1

try redirecting to previous page redirectin will cause the browser to make a new http request refreshing the page content to get the previous page address you can use HTTP_REFERER

$previousPage = $_SERVER["HTTP_REFERER"];
header('Location: '.$previousPage);

this will cause the browser to re-navigate to the previous page
