从数据库中取出最近三十天的数据并生成柱状图的代码,需要的朋友可以参考下。
在终端用cd 命令进入文件目录说明:此处例子我是拿项目中的一个例子讲解的。
1、新建一个项目 :用终端输入:zf create project Airline 格式:zf create action project project-name 备注:这些格式可以在终端输入zf 查看
2、新建一个action :zf create action dirgramshow index 格式:zf create action action-name controller-name
3、新建一个 model :zf create db-table flightinformation
action 层代码:indexController.php
代码如下:
public function indexAction ()
{
// action body
$db = new Application_Model_DbTable_Flightinformation();
/*获取最近30天内的数目
* select day(boo_time) as day,count(boo_autoid)as count,boo_time from bookinformation
where flag_pass=0 and date_sub(now(), interval 30 day)group by DATE_FORMAT(boo_time,'%m %d')
*/
$sql = "select DATE_FORMAT(boo_time,'%m-%d') as day,count(boo_autoid)as count from bookinformation " .
"where flag_pass=0 and date_sub(now(), interval 30 day)"group by DATE_FORMAT(boo_time,'%m %d')";
$result = $db->getAllInfo($sql)->fetchAll();
$this->view->result=$result;
}
view 层代码:dirgramshow.phtml
代码如下:
model 层代码:Flightinformation.php
代码如下:
class Application_Model_DbTable_Flightinformation extends Zend_Db_Table_Abstract
{
protected $_name = 'flightinformation';
public function getAllInfo($sql){
$adapter = Zend_Registry::get('db');
$flightinformation = $adapter->query($sql);
return $flightinformation;
}
}
最后的效果图如下:

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
