PHP怎么判断多维数组中是否包含空值

$arr=array(
    'listid'  => array('', 5),
    'title'   => array('', 38),
    'type'    => array('', '我有'),
    'count'   => array('', 3),
    'content' => array('无','无'),
);

$t = call_user_func_array('array_map', array_merge(array(null), $arr));
foreach($t as $k=>$v) if(array_diff($v, array('')) != $v) unset($t[$k]);
$t = count($t) == 1 ? array_chunk(current($t), 1) : call_user_func_array('array_map', array_merge(array(null), $t));
print_r(array_combine(array_keys($arr), $t));

Array
(
    [listid] => Array
        (
            [0] => 5
        )

    [title] => Array
        (
            [0] => 38
        )

    [type] => Array
        (
            [0] => 我有
        )

    [count] => Array
        (
            [0] => 3
        )

    [content] => Array
        (
            [0] => 无
        )

)
