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
