无法从codeigniter中的cookie获取关联数组变量

Question

i seem to be stuck at this problem for quiet a few time, basically i have used cookie in codeigniter, and passed an array with different names to different functions, the code to set the cookie is

$data = array (
            'client_block_ID'  => $client_block_ID,
            'client_unit_ID'   => $client_unit_ID,
            'blockUnits'       => $blockUnits
        );

            $cookieName ='tab'.$counter;

            $cookie = array(
                'name'   => $cookieName,
                'value'  => $data,
                'expire' => '86500',
        );

            $this->input->set_cookie($cookie); 

now i just dont know how to get the variables inside the array i.e what will be the syntax to get client_block_ID??

Now your cookie array will look like this.........

$cookie = array(
            'name'   => $cookieName,
            'value'  => array(
                               'client_block_ID'  => $client_block_ID,
                               'client_unit_ID'   => $client_unit_ID,
                               'blockUnits'       => $blockUnits
                        );
            'expire' => '86500',
           );

So to get your client_block_ID from your $cookie array you have to loop through that array like below.

foreach($cookie as $c)
{
    echo $c['name'];
    foreach($c['value'] as $v)
    {
        echo $v['client_block_ID'];
    }
}
