$LinkID =mysql_connect('localhost:3307','root',*******);
mysql_select_db('web_his',$LinkID);
mysql_query("set names utf8");

/* 创建事务 */
mysql_query('START TRANSACTION') or exit(mysql_error());
$ssql1="insert into pf_item values('22','我们','30')"; //执行sql 1
if(!mysql_query($ssql1)){
echo $ssql1.mysql_errno().":".mysql_error()."
";
mysql_query('ROLLBACK') or exit(mysql_error());//判断当执行失败时回滚

exit;
}
$ssql1="insert into pf_item values('21','hell','10')"; //执行sql 2
if(!mysql_query($ssql1)){
echo $ssql1.mysql_errno().":".mysql_error()."
";
mysql_query('ROLLBACK') or exit(mysql_error());//判断当执行失败时回滚
