如何不打印与已使用php脚本登录的用户的会话名称相同的mysql表值

<?php
// 获取当前会话名称
$sessionName = session_name();

// 连接到MySQL数据库
$servername = "your_servername";
$username = "your_username";
$password = "your_password";
$dbname = "your_dbname";

$conn = mysqli_connect($servername, $username, $password, $dbname);

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

// 查询MySQL表
$sql = "SELECT * FROM your_table WHERE session_name_column != '$sessionName'";
$result = mysqli_query($conn, $sql);

// 打印查询结果
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "列1: " . $row["column1"] . ", 列2: " . $row["column2"] . "<br>";
    }
} else {
    echo "没有匹配的结果";
}

// 关闭数据库连接
mysqli_close($conn);
?>
