PHP和MYSQL根据日期查找记录

$servername = "数据库服务器地址";
$username = "用户名";
$password = "密码";
$dbname = "数据库名";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

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

$date = "2022-01-01"; // 要查找的日期

$sql = "SELECT * FROM records WHERE date = '$date'";

$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出每一行记录
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Date: " . $row["date"]. "<br>";
    }
} else {
    echo "没有找到记录";
}

$conn->close();
