How to clear $_POST after page load?

Question

PHP

Hello everyone, I can't clear $_POST after page load.

Form - Passing $_POST to itself - Then the script works, and it is necessary that $_POST be cleared when the page is updated, trying unset does not help. How to make $_POST only work for 1 page load?

Answer 1

In general, try to redirect to the same URL, if I understand your problem correctly.
For example:
header('Location: /test.php');

Answer 2

Read the http specification. $_POST is just a variable that php fills with the next request. If a POST request receives a 200 response, the browser saves the previously sent data in order to send it again before the GET request.
And the fact that you have an error falls out - look for where you call echo, or any other function that sends information to php: // stdout

Answer 3

Redirect to the same page after a POST request.

Answer 4

I could be wrong, but try unset($_POST);
