将值插入数组

Question

多维数组：每个记录都有一个标题和数组，其中包含星期几作为键和值。我正在尝试将这些值插入现有数组的星期几（基于键）。 代码：

foreach($records as $rec)
        {

             $row = array(
                            'title' => $rec['title'], 
                            'Monday' => '', 
                            'Tuesday'=> '',
                            'Wednesday'=> '',
                            'Thursday' =>'', 
                            'Friday'   => '');


            foreach($rec['dates'] as $dtow)
            {
                $dow = explode(' ', $dtow)[0];
                $value = explode(' ', $dtow)[1];

                if($dow....blah blah that's where I'm getting lost...

            }
             $data[] = $row;
        }

任何建议都将受到赞赏。

EDITED： 对不起，那可能更好......
