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
复制代码代码如下:

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)<=date(boo_time)
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)<=date(boo_time) " .
"group by DATE_FORMAT(boo_time,'%m %d')";
$result = $db->getAllInfo($sql)->fetchAll();
$this->view->result=$result;
}

view 层代码：dirgramshow.phtml
复制代码代码如下:

myChart.setTooltipOffset(3);
myChart.setSize(616, 321);
/*myChart.setBackgroundImage('<?php

myChart.draw();
}
