How to return to previous page and refresh it in php or javascript?

Question

How can user return to the page he came from, and refresh its content, using PHP or javascript.

I've used this to get back to the page :

    header("Location: javascript:history.back(-1)");

but it needs to be refreshed after that.

Answer 1

You cannot execute javascript in a PHP script.

In PHP you can make use of the $_SERVER["HTTP_REFERER"] variable in the header() statement like so

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

Its always a good idea to follow a header() statement with an exit or code execution will continue through the rest of the script as normal.

Answer 2

If you just want to use javascript you can use window.history.back()

function goBack() {
    window.history.back();
}
