2. PHP中使用事务的实例

   <?php
   $username = "mysql";
   $password = "**************";
   $dsn = "mysql:dbname=data_base;host=127.0.0.1";
   $dbh = new PDO($dsn, $username, $password);
   if (!$dbh) {
       die('数据库连接失败');
   }
   try {
       $dbh->setAttribute(\PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION);
       $dbh->beginTransaction();
   
       $user_name = "test12345";
       $pass_word = "test12345";
       $nick_name = "测试用昵称";
       $sql1 = "INSERT INTO `user`(user_name, pass_word, nick_name)VALUES(:user_name, :pass_word, :nick_name)";
       $sth = $dbh->prepare($sql1);
       $sth->bindParam('user_name', $user_name);
       $sth->bindParam('pass_word', $pass_word);
       $sth->bindParam('nick_name', $nick_name);
       $sth->execute();
       $user_id = $dbh->lastInsertId();
       unset($sth);
   
       $user_coin = 0;
       $insert_time = time();
       $sql2 = "INSERT INTO `user_coin`(user_id, user_coin, insert_time)VALUES(:user_id, :user_coin, :insert_time)";
       $sth = $dbh->prepare($sql2);
       $sth->bindParam('user_id', $user_id);
       $sth->bindParam('user_coin', $user_coin);
       $sth->bindParam('insert_time', $insert_time);
       $sth->execute();
       unset($sth);
   
       $dbh->commit();
       die('数据库操作成功');
   } catch (PDOException $e) {
       $dbh->rollback();
       die('数据库操作失败');
   }
