Get a list of all state in yii

Question

This is my code:

for ($i=0; $i < count($rights); $i++) {
    $this->setState($rights[$i], true);
}

Here I am setting the setState dynamically, but I want to get all of states in a list. I did not find any references about this. I only found this:

Yii::app()->user->getState('name');

But this is not helping me. How can I get a list of all states in yii? thx

According to the API of CWebUser, there's no function for that purpose.

According to the code of setState, you can see that it saves the values in a session and that there's no another way of "storing" the used states. (Like an array of all created states)

public function setState($key,$value,$defaultValue=null)
{
    $key=$this->getStateKeyPrefix().$key;
    if($value===$defaultValue)
        unset($_SESSION[$key]);
    else
        $_SESSION[$key]=$value;
}

One solution is manually going through all the existing sessions ($_SESSION) but in my opinion it's not very efficient idea.

Another solution is to have a property/variable (array) to hold all the states that you've created and than using a foreach loop, use getState.
