?php
// 假定數(shù)據(jù)庫(kù)用戶(hù)名：root，密碼：123456，數(shù)據(jù)庫(kù)：codingdict
$con=mysqli_connect("localhost","root","123456","codingdict");
if (mysqli_connect_errno($con))
{
  echo "連接 MySQL 失敗: " . mysqli_connect_error();
}
// 關(guān)閉自動(dòng)提交
mysqli_autocommit($con,FALSE);
// 插入數(shù)據(jù)
mysqli_query($con,"INSERT INTO websites (name, url, alexa, country)
VALUES ('百度','https://www.baidu.com/','4','CN')");
mysqli_query($con,"INSERT INTO websites (name, url, alexa, country)
VALUES (Facebook','https://www.facebook.com/','2','USA')");
// 提交事務(wù)
mysqli_commit($con);
//回滾事務(wù)
mysqli_rollback($con);
// 關(guān)閉連接
mysqli_close($con);
