在php中将复选框值插入数据库表中

<form method="POST" action="insert.php">
  <input type="checkbox" name="interests[]" value="music">音乐
  <input type="checkbox" name="interests[]" value="sports">体育
  <input type="checkbox" name="interests[]" value="movies">电影
  <input type="submit" value="提交">
</form>

<?php
// 连接数据库
$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 获取复选框值
$interests = $_POST['interests'];

// 将复选框值插入数据库
foreach ($interests as $interest) {
    $sql = "INSERT INTO interests (interest) VALUES ('$interest')";
    if ($conn->query($sql) === TRUE) {
        echo "插入成功";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

// 关闭数据库连接
$conn->close();
?>

CREATE TABLE interests (
  id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  interest VARCHAR(30) NOT NULL
);
