I have a page which,
If a variable is set(in a session) it will do an action, then it unsets the session.
Now it has to refresh itself.
This is where i am stuck.
Is there a way to get the exact url to the current page?
or is there a function to do this?
so header('location: ???');

Most people know it can be done by hand by holding the shift key and clicking the “Refresh” (on IE) or “Reload” (on Navigator) buttons.
Use the header () Function to Periodically Refresh the Page in PHP We can use the header () function to refresh the page in PHP. We write the Refresh header inside the header () function and specify the time interval for refreshing the page. For example, write a header () function and specify the time interval of 1 second as header ("Refresh:1").
In the PHP code above, we sent a Refresh header to the browser by using PHP’s header function. This meta refresh header tells the browser that it should refresh the current page after five seconds. Obviously, you can change the $refreshAfter variable to suit your own needs.
Solid Tip: PHP is limited to using a meta tag to actually ‘refresh’ a page. ‘Redirecting’ a page is another story. The term ‘refresh’ suggests that a page existed already.
This article will introduce some methods to return to the previous page in PHP. The HTTP_REFERER request header returns the URL of the page from where the current page was requested in PHP. The header enables the server to acknowledge the location from where the users are visiting the current page.
header('Location: '.$_SERVER['REQUEST_URI']); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
