如何从PHP和MySQL数据库中获取与当前日期相等的日期？

<?php
// 获取当前日期
$currentDate = date('Y-m-d');

// 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);

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

// 构建查询语句
$sql = "SELECT * FROM your_table WHERE DATE(date) = '$currentDate'";

// 执行查询
$result = $conn->query($sql);

// 处理结果集
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // 处理或输出所需的数据
        echo "日期: " . $row["date"] . "<br>";
    }
} else {
    echo "没有找到与当前日期相等的日期。";
}

// 关闭数据库连接
$conn->close();
?>
