PHP 事务处理数据实现代码

public function insertUser ($userArray){ 
foreach ($userArray as $key => $value) { 
@$field .= "$key,"; 
@$content .= "'$value',"; 
} 
$field = ereg_replace(',$', '', $field); 
$content = ereg_replace(',$', '', $content); 

$db = db_connect(); //连接数据库 

$db->autocommit(FALSE); //设置为非自动提交――事务处理 

$sql1 = "INSERT INTO t_user (".$field.") VALUES (".$content.")"; 
$result1 = $db->query($sql1); 

$sql2 = "INSERT INTO t_userpost (f_username) VALUES ('".$userArray['f_username']."')"; 
$result2 = $db->query($sql2); 

if ($result1 && $result2) { 
$db->commit(); //全部成功，提交执行结果 
echo '提交'; 
} else { 
$db->rollback(); //有任何错误发生，回滚并取消执行结果 
echo '回滚'; 
} 
$db->close(); 
}
