当filter_input返回不正确的cookie值时

Question

I set cookie by this code

setcookie($cookieName, $value);

And get cookie by this

filter_input(INPUT_COOKIE, $cookieName);

But I get wrong value. Can you help?

Answer 1

Look how you use the code written by you, if you perform both actions on one script, then this is a logical result. Try this instead:

Set cookie:

setcookie($cookieName, $value);

Update your web page. And then get cookie:

filter_input(INPUT_COOKIE, $cookieName);

Hope this is resolve your issue.
