Question

当前正在做一个需要我将CSV文件中的数据导入数据库的项目，这是文件的数据示例：

|   id_attendance   |   name   |   date   |  time   |
-----------------------------------------------------
|        001        |   lily   |01.01.2018|  07:00  |
|        002        |  thomas  |01.01.2018|  07:02  |
|        003        |   lily   |01.01.2018|  19:00  |
|        004        |  thomas  |01.01.2018|  19:02  |
-----------------------------------------------------

与此同时，我需要将这些数据导入此类表

|   id_attendance   |   name   |   date   |  time_in  |  time_out  |
--------------------------------------------------------------------
|        001        |   lily   |01.01.2018|  07:00    |   19.00    |
|        002        |  thomas  |01.01.2018|  07:02    |   19.02    |
--------------------------------------------------------------------

这需要我自动将时间字段分为time_in和time_out。到目前为止，我已经完成了csv导入，这是我的代码

importcsv_m.php 模型

function importCSV()
{
    $count=0;
    $fp = fopen($_FILES['userfile']['tmp_name'],'r') or die("can't open file");
    while($csv_line = fgetcsv($fp,1024))
    {
        $count++;
        if($count == 1)
        {
            continue;
        }
        for($i = 0, $j = count($csv_line); $i < $j; $i++)
        {
            $insert_csv = array();
            $insert_csv['id_attendance'] = $csv_line[0];
            $insert_csv['name'] = $csv_line[1];
            $insert_csv['date'] = $csv_line[2];
            $insert_csv['time'] = $csv_line[3];
        }
        $i++;
        $data = array(
            'id_attendance' => $insert_csv['id_attendance'] ,
            'name' => $insert_csv['name'],
            'date' => $insert_csv['date'],
            'time' => $insert_csv['time'],
           );
        $data['crane_features']=$this->db->insert('attendance', $data);

    }       
    fclose($fp) or die("can't close file");
    $data['success']="success";
}

但是它仅导入数据而不会分隔时间（没有time_in和time_out）

我想知道我是否可以导入一个数组并将其分为两个？

我创建了一些代码，试图匹配每个班次的开始和结束。这是通过查找匹配的开始记录，然后为结束时间添加数据来实现的。如果找不到匹配的起始记录，则它将存储此数据（假设这是起始记录）。找到结束记录后，开始记录将从$attendancies中删除，因为下一条记录可能是新的班次...

function importCSV()
{
    $fp = fopen($_FILES['userfile']['tmp_name'],'r') or die("can't open file");
    // Ignore header line
    $header = fgetcsv($fp);
    // Array to store the partial records
    $attendancies = [];
    while($csv_line = fgetcsv($fp))
    {
        // Key to identify first part of record (Name and date)
        $key = $csv_line[1]."/".$csv_line[2];
        if ( isset($attendancies[$key]) ){
            $start = $attendancies[$key];
            // Extract data from first part of record and add in end date from current row
            $data = array(
                'id_attendance' => $start[0] ,
                'name' => $start[1],
                'date' => $start[2],
                'time_in' => $start[3],
                'time_out' => $csv_line[3],
            );
            $data['crane_features']=$this->db->insert('attendance', $data);
            // Remove partial record
            unset($attendancies[$key]);
        }
        else    {
            // Store partial record
            $attendancies[$key] = $csv_line;
        }
    }
    fclose($fp) or die("can't close file");
    $data['success']="success";
}

CSV导入具有不同数组的代码点火器
