在PHP中，mysqli 已经很好的封装了mysql事务的相关操作。如下示例：
view plain copy to clipboard print ?
$sql1 = “update User set ScoreCount = ScoreCount +10 where ID= ‘123456’”; $sql

在这里，我们再使用 php mysql 系列函数执行事务。
view plain copy to clipboard print ?
$sql1 = “update User set ScoreCount = ScoreCount +10 where ID= ‘123456’”; $sql2 = “update ScoreDetail set FScore = 300 where ID= ‘123456’”; $sql3 = “insert into ScoreDetail ID,Score) values (‘123456’,60)”; $conn = mysql_connect(‘localhost’,’root’,”); mysql_select_db(‘DB_Lib2Test’); mysql_query(‘start transaction’); //mysql_query(‘SET autocommit=0’); mysql_query($sql1); mysql_query($sql2); if(mysql_errno ()){ mysql_query(‘rollback’); echo ‘err’; }else{ mysql_query(‘commit’); echo ‘ok’; } // mysql_query(‘SET autocommit=1’); // mysql_query($sql3);
在这里要注意，
MyISAM：不支持事务，用于只读程序提高性能 InnoDB：支持ACID事务、行级锁、并发 Berkeley DB：支持事务
