使用条件mysql php获取n和n+6之间的记录

$query = "SELECT * FROM my_table WHERE column_name >= $n AND column_name <= ($n + 6)";

<?php
// 建立与MySQL数据库的连接
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

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

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

// 获取n和n+6之间的记录
$n = 10; // 替换为实际的值
$query = "SELECT * FROM my_table WHERE column_name >= $n AND column_name <= ($n + 6)";
$result = $conn->query($query);

// 处理结果集
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // 对每条记录进行处理
        echo "字段1: " . $row["column1"] . ", 字段2: " . $row["column2"] . "<br>";
    }
} else {
    echo "没有符合条件的记录";
}

// 关闭连接
$conn->close();
?>
