Compte tenu du fait que zendframework2 dispose de relativement peu de tutoriels en Chine, j'ai eu l'idée d'écrire cet article technique sur le framework zf2, dans l'espoir d'aider ceux qui en ont besoin.
1. configautoloadglobal.php
<?php //php中文网 www.php.cn return array( 'db' => array( 'driver' => 'pdo', 'driver_options' => array( \PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'' ) ) );
2. configautoloadlocal.php
<?php //php中文网 www.php.cn return array( 'db' => array( 'dsn' => 'mysql:dbname=testdb;hostname=localhost', 'username' => 'root', 'password' => 'root', 'prefix' => 'phpcn_' ), );

4. moduleApplicationviewpaginationtmpl.phtml
public function getServiceConfig() { return array( 'factories'=>array( 'Application\Model\Db'=>function($sm){ $service=new Model\Db($sm); return $service; }, 'Db\Adapter'=>function($sm){ $configs=$sm->get('Config'); $adapter = new \Zend\Db\Adapter\Adapter($configs['db']); return $adapter; }, 'Db\Feature'=>function($sm){ $configs=$sm->get('Config'); $Feature=new \Application\Model\TableNamePrefixFeature($configs['db']['prefix']); return $Feature; }, 'Db\Padapter'=>function($sm){ $Padapter=new \Zend\Paginator\Adapter\DbSelect($sm->get('Application\Model\Db')->select,$sm->get('Db\Adapter')); return $Padapter; }, 'Db\Paginator'=>function($sm){ $Paginator=new \Zend\Paginator\Paginator($sm->get('Db\Padapter')); return $Paginator; }, ), 'abstract_factories'=>array('Application\Services\CommonDbAbstractFactory') ); }
5. moduleApplicationsrcApplicationServicesCommonDbAbstractFactory.php
<?php if ($this->pageCount): ?> <p class="pageX"> <?php if (isset($this->previous)): ?> <a href="<?php echo $this->url().'?p='.$this->previous;?>">< 前一页</a> | <?php else: ?> <span>< 前一页</span> | <?php endif; ?> <?php foreach ($this->pagesInRange as $page): ?> <?php if ($page != $this->current): ?> <a href="<?php echo $this->url().'?p='.$page;?>"><?php echo $page;?></a> | <?php else: ?> <?php echo $page; ?> | <?php endif; ?> <?php endforeach; ?> <?php if (isset($this->next)): ?> <a href="<?php echo $this->url().'?p='.$this->next;?>">下一页 ></a> <?php else: ?> <span>下一页 ></span> <?php endif; ?> </p> <?php endif; ?>
6. php
<?php //php中文网 www.php.cn namespace Application\Services; use Zend\ServiceManager\AbstractFactoryInterface; use Zend\ServiceManager\ServiceLocatorInterface; class CommonDbAbstractFactory implements AbstractFactoryInterface { public function canCreateServiceWithName(ServiceLocatorInterface $locator, $name, $requestedName) { $a=explode(':',$name); if(!empty($a[0]) && $a[0]=='db'){ return true; } return false; } public function createServiceWithName(ServiceLocatorInterface $locator, $name, $requestedName) { $a=explode(':',$name); return $locator->get('Application\Model\Db')->get($a[1]); } }
7. moduleApplicationsrcApplicationModelTableNamePrefixFeature.php
<?php //php中文网 www.php.cn namespace Application\Model; use Zend\Db\TableGateway\TableGateway; use Zend\ServiceManager\ServiceManager; class Db { public function construct(ServiceManager $sm){ $this->sm=$sm; } public function get($tablename=null) { $configs=$this->sm->get('Config'); $adapter=$this->sm->get('Db\Adapter'); $dbFeature=$this->sm->get('Db\Feature'); $this->db=new TableGateway($tablename,$adapter,$dbFeature); $this->select=$this->db->getSql()->select(); return $this; } public function fetch(){ return $this->db->selectWith($this->select); } public function getSql(){ return $this->select; } public function getTableGateway(){ return $this->db; } public function select($where = null){ return $this->db->select($where); } public function insert($set){ return $this->db->insert($set); } public function update($set, $where = null){ return $this->db->update($set,$where); } public function delete($where){ return $this->db->delete($where); } public function call($functionName,$args){ $this->select=call_user_func_array(array($this->select,$functionName),$args); return $this; } }
8. moduleApplicationsrcApplicationControllerIndexController.php
<?php //php中文网 www.php.cn namespace Application\Model; use Zend\Db\TableGateway\Feature\AbstractFeature; class TableNamePrefixFeature extends AbstractFeature { protected $prefix=null; public function construct($prefix=null) { if(null!==$prefix) { $this->setPrefix($prefix); } } public function setPrefix($prefix) { $this->prefix=$prefix; } public function postInitialize() { if(null!==$this->prefix){ $this->tableGateway->getSql()->setTable($this->prefix.$this->tableGateway->table); } } }
