要实现本功能的条件是环境 mysql 5.2 /php 5 支持事务的table 类型 需要InnoDB ,有了这些条件你就可以做上面的实现了,这个事物回滚操作是大项目经常用到的,像银行,电子商务等都会用到,有需要的朋友可以参考一下。

近期项目软件升级到支持事务处理,做个示例供大家学习参考

$ssql1="insert into pf_item values('22','我们','30')";  //执行sql 1
if(!mysql_query($ssql1)){
   echo $ssql1.mysql_errno().":".mysql_error()."
";

   exit;
}
$ssql1="insert into pf_item values('21','hell','10')";  //执行sql 2
if(!mysql_query($ssql1)){
  echo $ssql1.mysql_errno().":".mysql_error()."
