How to define and retrieve cookie value as array in CakePHP?

Answer 1

You don’t need to do anything special as Cake’s CookieComponent handle’s arrays seamlessly.

In your controller, make sure you’ve included the CookieComponent:

var $components = array('Cookie');

In your action, to write an array:

$this->Cookie->write('test', array('value1', 'value2'));

And then to read it back:

$test = $this->Cookie->read('test');  // $test will be an array
