本文实例讲述了php事务回滚简单实现方法。分享给大家供大家参考,具体如下:
$servername="localhost"; $username="root"; $password="admin"; $dbname="test"; try{ $conn=new PDO("mysql:host=$servername;dbname=$dbname",$username,$password); $conn->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); //开始事务 $conn->beginTransaction(); $conn->exec("INSERT INTO `hello`(`firstname`,`lastname`,`email`)VALUES('YE','XIAMING','yexianming@163.com')"); $conn->exec("INSERT INTO `hello`(`firstname`,`lastname`,`email`)VALUES('YE','CONG','yecong@163.com')"); $conn->exec("INSERT INTO `hello`(`firstname`,`lastname`,`email`)VALUES('FANG','MENG','fangmeng@168.com')"); //提交事务 $conn->commit(); echo "New records created successfully!"; }catch(PDOException $e){ //回滚事务 $conn->rollBack(); echo $sql."<br>".$e->getMessage(); } $conn=NULL;
希望本文所述对大家PHP程序设计有所帮助。
