使用PHP从MySQL添加天数到当前日期

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// 获取当前日期
$current_date = date("Y-m-d");

// 添加天数
$days_to_add = 10;
$new_date = date("Y-m-d", strtotime($current_date . " + " . $days_to_add . " days"));

// 插入新日期
$sql = "INSERT INTO myTable (date) VALUES ('$new_date')";

if ($conn->query($sql) === TRUE) {
  echo "新日期插入成功";
} else {
  echo "Error: " . $sql . "<br>" . $conn->error;
}

// 关闭连接
$conn->close();

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// 获取当前日期
$current_date = date("Y-m-d");

// 添加天数
$days_to_add = 10;
$new_date = date("Y-m-d", strtotime($current_date . " + " . $days_to_add . " days"));

// 插入新日期
$sql = "INSERT INTO myTable (date) VALUES ('$new_date')";

if ($conn->query($sql) === TRUE) {
  echo "新日期插入成功";
} else {
  echo "Error: " . $sql . "<br>" . $conn->error;
}

// 关闭连接
$conn->close();
