本文實(shí)例講述了ZendFramework2連接數(shù)據(jù)庫操作。分享給大家供大家參考，具體如下：
相對(duì)于zf1,來說,zf2讓我們對(duì)于數(shù)據(jù)庫這方面的操作我的個(gè)人感覺是對(duì)于字段起別名簡單了,但是對(duì)數(shù)據(jù)庫的操作雖然配置寫好的就基本不需要?jiǎng)恿耍沁€是比1的配置要繁瑣,
還是那句話，大家可以去看看源碼。。。
Module.php 里面添加
public function getServiceConfig()
{
return array(
'factories' => array(
'Student\Model\StudentTable' => function($sm) {
$tableGateway = $sm->get('StudentTableGateway');
$table = new StudentTable($tableGateway);
return $table;
},
'StudentTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Student());
return new TableGateway('cc_user', $dbAdapter, null, $resultSetPrototype);//table Name is cc_user
},
),
);
}
student.php 這個(gè)是Model/Student.php
namespace Student\Model;
class Student
{
public $id;
public $name;
public $phone;
public $mark;
public $email;
public function exchangeArray($data)//別名
{
$this->id = (!empty($data['cc_u_id'])) ? $data['cc_u_id'] : null;
$this->name = (!empty($data['cc_u_name'])) ? $data['cc_u_name'] : null;
$this->phone = (!empty($data['cc_u_phone'])) ? $data['cc_u_phone'] : null;
$this->mark = (!empty($data['cc_u_mark'])) ? $data['cc_u_mark'] : null;
$this->email = (!empty($data['cc_u_email'])) ? $data['cc_u_email'] : null;

}
StudentTable.php Model/StudentTable.php

Student/IndexController.php 調(diào)用數(shù)據(jù)庫
public function indexAction(){
/* return new ViewModel(array(
'students' => $this->getStudentTable()->fetchAll(), //不分頁
));*/
$page=$this->params('page');//走分頁 在model.config.php里面設(shè)置:
/* model.config.php
'defaults' => array(
'controller' => 'Student\Controller\Index',
'action' => 'index',
'page'=>'1',
),
*/
$paginator = $this->getStudentTable()->fetchAll(true);
// set the current page to what has been passed in query string, or to 1 if none set
$paginator->setCurrentPageNumber((int)$this->params()->fromQuery('page', $page));
// set the number of items per page to 10
$paginator->setItemCountPerPage(10);
return new ViewModel(array(
'paginator' => $paginator //模板頁面調(diào)用的時(shí)候的名字
));
//print_r($this->getStudentTable()->fetchAll());
}
在模板頁面的調(diào)用
<?php foreach ($this->paginator as $student) : ?>
<tr id="<?php echo $this->escapeHtml($student->id);?>">
<td><?php echo $this->escapeHtml($student->id);?></td>
<td><?php echo $this->escapeHtml($student->name);?></td>
<td><?php echo $this->escapeHtml($student->phone);?></td>
<td><?php echo $this->escapeHtml($student->email);?></td>//應(yīng)用了在Student.php的別名
<td><?php echo $this->escapeHtml($student->mark);?></td>
<td><a href='#' class='icol-bandaid editUserInfo'></a>
<a href='#' class='icol-key changePwd'></a>
<a herf='#' class='icol-cross deleteStud'></a>
</td>
</tr>
