以下是一个示例代码,演示了如何在CodeIgniter 3中处理事务查询: 代码语言:txt 复制 public function transactionExample() { // 开启事务 $this->db->trans_start(); // 执行查询操作 $this->db->query('INSERT INTO table1 (column1) VALUES ("value1")'); $this->db->query('UPDATE table2 SET colu...

https://域名/index.php/users/add_user/KING/18/北京 解释:调用users控制器的add_user方法,而add_user方法向User_model模型的add_user方法传递了一个数组$user_data,数组有3个参数,分别是$name、$age、$city,在URL中,KING/18/北京就是这三个参数的传递,这三个参数由users控制器接收,然后调用模型进行创建用户。

The fixes to the ODBC driver mean that you can no longer use the query builder with it, nor the escape() functions. On the plus side, it now has actual query binding, as opposed to emulated. The ODBC fixes are not backwards compatible, hence the bump in version number. We are also...
