<?php
if (isset($_POST['email'])) {
    include 'dbconn.php';
    $email = $conn->real_escape_string($_POST['email']);

    $sql = $conn->query("SELECT id from users WHERE userEmail='$email'");

    if (!empty($sql) && $sql->num_rows > 0) {

        $token = "poiuytrewqlkjhgfdsamnbvcxz1234567890";
        $token = str_shuffle($token);
        $token = substr($token, 0, 10);

        $conn->query("UPDATE users SET token = '$token', 
                        tokenExpire = DATE_ADD(NOW(), INTERVAL 5 MINUTE)

tokenExpire已在我的数据库中更新，但不仅已更新令牌，而且未在数据库中创建令牌。这是通过令牌忘记了密码系统，并通过邮件将其发送到的，但是我只是在做此系统的开始。

请帮助我，因为我是初学者，很长一段时间都无法解决此问题。

Answer 1

检查令牌字段类型（如果其为整数或Varchar）。如果是整数，则转换为Varchar（255）。

令牌未在mysql数据库中更新
