php里面怎么把数组里面的二维数组转化成obj类型的呢？

[奔波在生活路上]

想把useridinfo这个数组转化成obj类型的怎么做呢？
试了下new ArrayObject($arr[$key])结果把整个都转化了，求大神帮忙。

$a = array(
  array(
    'userIdInfo' => array( 'uid' => '100000113', 'type' => 'ZXIN_IDTYPE::IDNA' ),
    'chgCreditValue' => 50
  ),
  array(
    'userIdInfo' => array( 'uid' => '10000110', 'type' => 'ZXIN_IDTYPE::IDNA' ),
    'chgCreditValue' => 150
  ),
);
foreach($a as &$v)  settype($v, 'object');
print_r($a);

Array
(
    [0] => stdClass Object
        (
            [userIdInfo] => Array
                (
                    [uid] => 100000113
                    [type] => ZXIN_IDTYPE::IDNA
                )

            [chgCreditValue] => 50
        )

    [1] => stdClass Object
        (
            [userIdInfo] => Array
                (
                    [uid] => 10000110
                    [type] => ZXIN_IDTYPE::IDNA
                )

            [chgCreditValue] => 150
        )

)
