How to use add, delete, modify and check in phpcms

1. Check

1. select($where = '', $data = '*', $limit = '', $order = '', $group = '', $key='')

/** * 执行sql查询 * @param $where 查询条件[例`name`='$name'] * @param $data 需要查询的字段值[例`name`,`gender`,`birthday`] * @param $limit 返回结果范围[例:10或10,10 默认为空] * @param $order 排序方式 [默认按数据库默认方式排序] * @param $group 分组方式 [默认为空] * @param $key 返回数组按键名排序 * @return array 查询结果集数组 */
Copy after login

2. listinfo($where = '', $order = '', $page = 1, $pagesize = 20, $key='' , $setpages = 10,$urlrule = '',$array = array(), $data = '*')

/** * 查询多条数据并分页 * @param $where * @param $order * @param $page * @param $pagesize * @return unknown_type */
Copy after login

3.get_one($where = '', $data = '*', $order = '', $group = '')

/** * 获取单条记录查询 * @param $where 查询条件 * @param $data 需要查询的字段值[例`name`,`gender`,`birthday`] * @param $order 排序方式 [默认按数据库默认方式排序] * @param $group 分组方式 [默认为空] * @return array/null 数据查询结果集,如果不存在,则返回空 */
Copy after login

4. query($sql)

/** * 直接执行sql查询 * @param $sql 查询sql语句 * @return boolean/query resource 如果为查询语句,返回资源句柄,否则返回true/false */
Copy after login

2. Add

1. insert($data, $ return_insert_id = false, $replace = false)

/** * 执行添加记录操作 * @param $data 要增加的数据,参数为数组。数组key为字段值,数组值为数据取值 * @param $return_insert_id 是否返回新建ID号 * @param $replace 是否采用 replace into的方式添加数据 * @return boolean */
Copy after login

2. insert_id()

/** * 获取最后一次添加记录的主键号 * @return int */
Copy after login

3. Change

3. update($data, $where = '')

/** * 执行更新记录操作 * @param $data 要更新的数据内容,参数可以为数组也可以为字符串,建议数组。 *             为数组时数组key为字段值,数组值为数据取值 * 为字符串时[例:`name`='phpcms',`hits`=`hits`+1]。 * 为数组时[例: array('name'=>'phpcms','password'=>'123456')] * 数组的另一种使用array('name'=>'+=1', 'base'=>'-=1');程序会自动解析为`name` = `name` + 1, `base` = `base` - 1 * @param $where 更新数据时的条件,可为数组或字符串 * @return boolean */
Copy after login

4. Delete

1. delete($where)

/** * 执行删除记录操作 * @param $where 删除数据条件,不充许为空。 * @return boolean */
Copy after login
