从多维数组中选择第一个工作日

Question

我有一个多维数组，如下所示。在当天的阵列中，它有各种各样的日子，有工作日和非工作日。现在我想先考虑first =“working”作为start_date 你可以帮帮我吗。感谢

Array
(
[error] => 0
[data] => Array
    (
        [start_date] => 2018-03-11
        [end_date] => 2018-03-21
        [days] => Array
            (
                [0] => Array
                    (
                        [type] => non_working
                        [sub_type] => weekend
                        [sub_sub_type] => 
                        [date] => 2018-03-11
                    )

                [1] => Array
                    (
                        [type] => working
                        [sub_type] => 
                        [sub_sub_type] => 
                        [full_date] => 2018-03-12
                    )

                [2] => Array
                    (
                        [type] => working
                        [sub_type] => 
                        [sub_sub_type] => 
                        [full_date] => 2018-03-13
                    )
           )
      )
)

我现在尝试这个：

$i=0;
$var = array();
foreach($arr['data']['days'][$i] as $var) {
    if($var['type'] == 'working') {
        break;
    }
}

返工$arr['data']['days'][$i]至$arr['data']['days']：

$start = null;
foreach($arr['data']['days'] as $var) {
    if($var['type'] == 'working') {
        $start = $var['date'];
        break;
    }
}
