Example
To set a cookie i.e. to create it and schedule for sending to the browser you need to create new \yii\web\Cookie class instance and add it to response cookies collection:
$cookie = new Cookie([
'name' => 'cookie_monster',
'value' => 'Me want cookie!',
'expire' => time() + 86400 * 365,
]);
\Yii::$app->getResponse()->getCookies()->add($cookie);
In the above we're passing parameters to cookie class constructor. These basically the same as used with native PHP setcookie function:
name- name of the cookie.value- value of the cookie. Make sure it's a string. Browsers typically aren't happy about binary data in cookies.domain- domain you're setting the cookie for.expire- unix timestamp indicating time when the cookie should be automatically deleted.path- the path on the server in which the cookie will be available on.secure- iftrue, cookie will be set only if HTTPS is used.httpOnly- iftrue, cookie will not be available via JavaScript.
