拆分日期和时间，然后放入其他列

我正在做一个小的约会项目。在我的CSV文件中，我有4列，分别是名称，员工ID，数据/时间，状态，在我的数据库列中是名称，empID，日期，timeIn，超时，状态。

我的csv文件的图片：（图片A）

这是我要保存在数据库中的内容：（图B）

enter image description here

示例输入CSV字符串：

Name,"Empoyee ID",Date/Time,Status
"Soriano, Jhoniel",901,"05/03/2019 1:01:03 PM",C/Out
"Soriano, Jhoniel",901,"05/04/2019 2:01:03 PM",C/In
"Soriano, Jhoniel",901,"05/04/2019 3:01:03 PM",C/Out
"Soriano, Jhoniel",901,"05/06/2019 4:01:03 PM",C/In
"Soriano, Jhoniel",901,"05/06/2019 5:01:03 PM",C/Out
"Soriano, Jhoniel",901,"05/07/2019 6:01:03 PM",C/In

有人可以给我一个肮脏的开端或任何想法来完成这项工作。

任何帮助都会受到赞赏。.

谢谢..

编辑：

我要感谢@jimmix给我一些入门的想法。

但是这是真实的情况，如果我不能很好地解释我的问题，很抱歉。

从我的CSV文件中，您可以获得在（图A）中可以找到的数据，然后使用表名“ tbldumpbio”将我的upload（）函数上传到我的phpmyadmin数据库中，

请参阅下面的表结构：

enter image description here

从我的表tbldumpbio数据中，我有一个名为processTimesheet（）的函数

代码如下：

public function processTimesheet(){
        $this->load->model('dbquery');          

            $query = $this->db->query("SELECT * FROM tbldumpbio");

            foreach ($query->result() as $row){

            $dateTimeExplArr = explode(' ', $row->datetimex);

            $dateStr = $dateTimeExplArr[0];
            $timeStr = $dateTimeExplArr[1];

            if($row->status='C/Out' and !isset($timeStr) || empty($timeStr) ){
                $timeStrOut ='';
            } else {
                $timeStrOut = $dateTimeExplArr[1];
            }

            if($row->status='C/In' and !isset($timeStr) || empty($timeStr) ){
                $timeStrIn ='';     
            } else {
                $timeStrIn = $dateTimeExplArr[1];   
            }

            $data = array(
                'ID' => '',
                'companyAccessID' => '',
                'name' => $row->name,
                'empCompID' => $row->empid,
                'date' => $dateStr,
                'timeIn' => $timeStrIn,
                'timeOut' => $timeStrOut,
                'status' => '',
                'inputType' => ''       
            );              
            $this->dbquery->modInsertval('tblempbioupload',$data);


            }
    }

此功能将向tblempbioupload添加另一个数据。但是，这是我得到的结果：

请参阅以下数据：

enter image description here

问题是：

  • 日期不能重复
  • 如果状态为“ C / In”，则应添加“时间输入”数据
  • 如果状态为“ C / Out”，则应添加超时数据

预期结果应该是这样的：

不是最短的，但可以工作：

print_r($csvStr);

给出输出：

  

---数组结果---

"Soriano, Jhoniel",901,05/07/2019,6:01:03,

使用：

file_put_contents('path-to-file', $csvStr);

最后将csv保存到文件。
