我想从一个表中检索使用php mysql发布的24小时后的所有记录。

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

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 构建查询语句
$sql = "SELECT * FROM your_table WHERE publish_date >= DATE_ADD(NOW(), INTERVAL 24 HOUR)";

// 执行查询
$result = $conn->query($sql);

// 处理结果集
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // 处理每一条记录
        echo "ID: " . $row["id"] . " - 标题: " . $row["title"] . "<br>";
    }
} else {
    echo "没有记录";
}

// 关闭数据库连接
$conn->close();
?>
