if (is_uploaded_file($_FILES['filename']['tmp_name'])) {
    echo "<h1>" . "File ". $_FILES['filename']['name'] ." Uploaded Successfully." . "</h1>";
    echo "<h2>Displaying contents:</h2>";
    readfile($_FILES['filename']['tmp_name']);
}

//Import uploaded file to Database
    //exclude the first row title
    $row = 1;
if(($handle = fopen($_FILES['filename']['tmp_name'], "r")) !== FALSE){
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($i=0; $i<=38; $i++){
if($firstRow) { $firstRow = false; }

由于图案是奇数和偶数行。

$row = 0;
$i = 0;

$container = array();
if(($handle = fopen($_FILES['filename']['tmp_name'], "r")) !== FALSE){

    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {

        if ($row > 2) {               

            if ($row % 2 == 0) {
                $i = $i - 6;
                $v = 'day';

            } else {
                $v = 'date';
            }

            foreach ($data as $column) {
                $container[$i][$v] = $column;
                $i++;
            }
        }                        
        $row++;
    }

fclose($handle);

}

foreach ($container as $value) {
     $import="INSERT into class(day, date) 
            values('".$value['day']."','".$value['date']."')";

    mysqli_query($link, $import) or die(mysqli_error($link));
}

$container应包含与当天配对的日期。像，

$container = [['day' => 'W1D1', 'date' => '19-Oct'], ['day' => 'W1D2', 'date' => '20-Oct']];

您可以使用循环插入数据库。
