php mysql查询1或0如何填充表的状态？

<?php
// 连接到MySQL数据库
$servername = "数据库服务器名称";
$username = "用户名";
$password = "密码";
$dbname = "数据库名称";

$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 准备INSERT语句
$status = 1; // 填充状态为1
$sql = "INSERT INTO status_table (status) VALUES ($status)";

// 执行INSERT语句
if ($conn->query($sql) === TRUE) {
    echo "状态填充成功";
} else {
    echo "状态填充失败: " . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>
