这就是我最终实现它的方式:
//$variable1Array = $this->Cookie->read('variable1'); -----> BEFORE
$variable1Array = $this->Cookie->read('Box.variable1'); -----> NOW
//$variable2Array = $this->Cookie->read('variable2'); -----> BEFORE
$variable2Array = $this->Cookie->read('Box.variable2'); -----> NOW
//$this->Cookie->write('variable2', $variable2Array, true, '2 months'); -----> BEFORE
$this->Cookie->write('Box.variable2', $variable2Array, true, '2 months'); -----> NOW
//$this->Cookie->write('variable1', $variable1Array, true, '2 months'); -----> BEFORE
$this->Cookie->write('Box.variable1', $variable1Array, true, '2 months'); -----> NOW
