Since the patterns are odd and even rows.
$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));
}
The $container should contain the date paired to the day. Like,
$container = [['day' => 'W1D1', 'date' => '19-Oct'], ['day' => 'W1D2', 'date' => '20-Oct']];
And you can use loop to insert into database.
