How to make a redirect to a page with a Get parameter?

Question

PHP

There is a page /personal/order/make/neworder.php that needs to be redirected to /personal/order/make/neworder.php?clear_cache=Y, but to avoid cycling. How to do it in php?

Answer 1

Redirecting is easy:
And in order to avoid cyclicity, you need to check that this get parameter is present, and then do not do an additional redirect. Otherwise, the redirect will repeat again and again, because. it's the same page.
Example:

if (!isset($_GET['clear_cache'])) {
    header('Location: http://blabla.net/personal/order/make/neworder.php?clear_cache=Y');
}
