$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;
