Question

我有一张学生详细信息表。我有两个csv文件，这些文件包含现有学生和新学生数据的更新信息。如果数据不在学生表中，这意味着学生离开了学校。

更新现有学生的新详细信息
如果学生离开学校更新状态为零
如果是新学生，则添加为新行（包含来自两个csv的详细信息）

以下是我的代码，但在第二个文件中没有更新信息。我附上我的代码。如果有人有简单的解决方案，请建议

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "student";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

if (isset($_POST['submit'])) {
    $sql = "SELECT * FROM e_student";
    $result_main = $conn->query($sql);
    $filea = $_FILES['filea'];

    $ext = pathinfo($_FILES['filea']['name'], PATHINFO_EXTENSION);

    if ($ext == "csv" && $_FILES["filea"]["error"] == 0) {
        $target = "upload/" . $_FILES["filea"]["name"];
        move_uploaded_file($_FILES["filea"]["tmp_name"], $target);

        if (($handle = fopen($target, "r")) !== FALSE) {

            $array = $fields = array();
            $i = 0;

            while (($row = fgetcsv($handle, 4096)) !== false) {
