为mysql数据库添加添加事务处理的方法

CREATE TABLE IF NOT EXISTS `test` (
`id` int(10) NOT NULL auto_increment,
`websitename` varchar(200) character set utf8 NOT NULL,
`websiteurl` varchar(200) character set utf8 NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

<?php
$con = mysql_connect("localhost", "root", "vertrigo");
//开始事务
mysql_db_query("mysqlnew","BEGIN");
$insertSql ="insert into test(websitename,websiteurl)values('脚本之家','https://www.jb51.net')";//该记录插入数据库
mysql_db_query("mysqlnew",$insertSql);
$insertSql ="insert into test(websitename,websiteurl)values('百度','http://www.baidu.com')";//该记录插入数据库
mysql_db_query("mysqlnew",$insertSql);
//结束事务事务
mysql_db_query("mysqlnew","COMMIT");
//开始事务
mysql_db_query("mysqlnew","BEGIN");
$insertSql ="insert into test(websitename,websiteurl)values('google','http://www.google.com.hk')";//该记录不插入数据库
mysql_db_query("mysqlnew",$insertSql);
//结束事务事务
mysql_db_query("mysqlnew","ROLLBACK");
//开始事务
mysql_db_query("mysqlnew","BEGIN");
$insertSql ="insert into test(websitename,websiteurl)values('bing','http://www.bing.com')";//该记录不插入数据库
mysql_db_query("mysqlnew",$insertSql);
?>
