Encodes and decodes authenticated and encrypted cookies in PHP.
First, create an instance of GuardedCookie with the name of the cookie you would like to encode; in this case, our cookie name is 'session'.
use GuardedCookie\GuardedCookie;
$guarded_cookie = new GuardedCookie('session', [
'hash_key' => 'something-super-super-secret',
'encryption_key' => 'something-even-more-more-secret',
]);Next, you decode the cookie value, do something with it, then encode it and output the cookie response header.
// The `get()` method fetches the cookie from `$_COOKIE` for you and decodes it.
$session = $guarded_cookie->get() ?: [];
$session['user_id'] = 12345;
// Somewhere before you output any data
// The `save()` method encodes your cookie with the value you pass and adds the
// proper response headers for you.
$guarded_cookie->save($session);
