php - yii登录如何记住用户名？

Question

在使用yii登录的时候，我将第二个参数$duration设置成86400，既将用户的登录信息保存到cookie里面24小时。

Yii::app()->user->login($identity,86400);

当我想要解析这个cookie的时候，发现cookie是这样的。

array(4) {
  ["CNZZDATA2724999"]=>
  string(48) "cnzz_eid=1338694115-1438177009-&ntime=1438182411"
  ["Hm_lvt_598eaf80391e655d10ebe38419b36fb2"]=>
  string(32) "1438310921,1438410705,1438589813"
  ["PHPSESSID"]=>
  string(26) "8ak62atemv5t4vc67hjrj1l705"
  ["abed3dd2114943c0bf392b4ae87e177b"]=>
  string(139) "d6991a57d52238c7b0b10d36c07f1fd9b715532ea:4:{i:0;s:2:"27";i:1;s:5:"endui";i:2;i:86400;i:3;a:2:{s:4:"role";s:1:"1";s:4:"name";s:5:"endui";}}"
}

但是我该怎么才可以解析这个cookie呢？是用什么方法？

Answer 1

// cookies
$cookie = array(
    'CNZZDATA2724999' => 'cnzz_eid=1338694115-1438177009-&ntime=1438182411',
    'Hm_lvt_598eaf80391e655d10ebe38419b36fb2' => '1438310921,1438410705,1438589813',
    'PHPSESSID' => '8ak62atemv5t4vc67hjrj1l705',
    'abed3dd2114943c0bf392b4ae87e177b' => 'd6991a57d52238c7b0b10d36c07f1fd9b715532ea:4:{i:0;s:2:"27";i:1;s:5:"endui";i:2;i:86400;i:3;a:2:{s:4:"role";s:1:"1";s:4:"name";s:5:"endui";}}' 
);
//正则
$regExp = '/(a:\d+:{.+)$/';

/*假设明确知道是哪个键存储的cookie值*/
$cookieUserInfo = end($cookie);
$getUserInfoStr = preg_match($regExp,$cookieUserInfo,$matchedStr);
$getUserInfo = $matchedStr[1] ? unserialize($matchedStr[1]) : array();
print_r($getUserInfo);

/*如果是随机某键某位置存储*/
$getUserInfo = array();
foreach($cookie as $cookieUserInfo){
    if(preg_match($regExp,$cookieUserInfo,$matchedStr)){
        $getUserInfo = unserialize($matchedStr[1]);
        break;
    }
}
print_r($getUserInfo);
