I got some cookie start by XYZ and I want to unset them when the user access to a specific route.
So I code :
foreach ($_COOKIE as $key => $value)
if (preg_match('/^XYZ/', $key))
unset($_COOKIE[$key]);
But the cookies still there. I really don't understand because when I do :
foreach ($_COOKIE as $key => $value)
if (preg_match('/^XYZ/', $key))
echo($_COOKIE[$key]);
... it works. So I wonder if it is possible to unset cookies like above.
重设Cookie,例如:
setcookie($key,"",time()-3600);
You can try this -
foreach ($_COOKIE as $key => $value) {
if (strpos($key, 'XYZ') === 0) { // check if name starts with 'XYZ'
setcookie($key, "", (time() - 3600) ); // Set the time which already expired
}
}
With preg_match
-
if (preg_match('/^XYZ/', $key)) {
setcookie($key, "", (time() - 3600) );
}
