这里有新鲜出炉的Zend Framework中文手册，程序狗速度看过来！
Zend Framework PHP开源框架
Zend Framework(简写ZF)是由 Zend 公司支持开发的完全基于 PHP5 的开源PHP开发框架，可用于开发 Web 程序和服务，ZF采用 MVC(Model–View-Controller) 架构模式来分离应用程序中不同的部分方便程序的开发和维护。
本文实例讲述了ZendFramework框架实现连接两个或多个数据库的方法。分享给大家供大家参考，具体如下：
配置文件：
<db>
<adapter>PDO_MSSQL</adapter>
<config>
<host>localhost</host>
<port>1433</port>
<username>sa</username>
<password>123456</password>
<dbname>edudb</dbname>
<pdoType>sqlsrv</pdoType>
</config>
</db>
<!-- 测试多数据库 -->
<db2>
<adapter>PDO_MSSQL</adapter>
<config>
<host>localhost</host>
<port>1433</port>
<username>sa</username>
<password>123456</password>
<dbname>test</dbname>
<pdoType>sqlsrv</pdoType>
</config>
</db2>
入口文件
//配置数据库连接
$db_config = $web_config->db->config->toArray();
//var_dump($db_config);
$db = Zend_Db::factory($web_config->db->adapter, $db_config);
//var_dump($db);
//exit;
//$db->query('set NAMES utf8');
//$db->getProfiler()->setEnabled(false);
Zend_Db_Table::setDefaultAdapter($db);
这里是默认的数据库
dao.php调用默认数据库
$db = &$this->getAdapter();
dao2.php连接其他数据库
function init() {
$web_config = $this->getCfg();
$this->db2_config = $web_config->db2->config->toArray();
//var_dump($this->db_config);
$this->db = Zend_Db::factory($web_config->db2->adapter, $this->db2_config);
Zend_Db_Table::setDefaultAdapter($this->db);
}
public function returnDb(){
return $this->db;
}
调用
$db = &$this->getAdapter();
还是会连接默认数据库。
直接使用
$this->db
就可以了
来看一下完整的dao2.php
<?php
class dao_dao2 extends Zend_Db_Table {
protected $cfg_;
function init() {
$web_config = $this->getCfg();
$this->db2_config = $web_config->db2->config->toArray();
//var_dump($this->db_config);
$this->db = Zend_Db::factory($web_config->db2->adapter, $this->db2_config);
Zend_Db_Table::setDefaultAdapter($this->db);
}
public function returnDb(){
return $this->db;
}
public function getData($table,$where = false, $order = 'id ASC', $pagesize = false, $offset = false, $count = false, $from = false, $join = false, $group = false) {
//$this->db = &$this->getAdapter();
$select = $this->db->select();
if ($where && is_array($where)) {
foreach ($where as $key => $val) {
//print_r($where);
if($val['type']==1){
$select->where($key, $this->convert2gbk($val['val']));
}else{
$select->orwhere($key, $this->convert2gbk($val['val']));
}
}
}
if (!$from)
$from = '*';
//echo $select."<br/>";
if ($pagesize) {
$select->limit($pagesize, $offset);
}
//echo $select."<br/>";
if (is_array($order)) {
foreach ($order as $value) {
$select->order($value);
}
} else {
$select->order($order);
}
//echo $select."<br/>";
$select->from($table, $count ? "COUNT(".$table.".id)" : $from);
if (is_array($group)) {
foreach ($group as $key => $val) {
$select->group($val);
}
if ($count) {
$result = $this->db->fetchAll($select);
//echo $select."<br/>";
return $result;
}
} else {
if ($count) {
$result = $this->db->fetchOne($select);
//echo $select."<br/>";
return $result;
}
}
if (is_array($join)) {
foreach ($join as $key => $val) {
//$select->join($key, $val[0], $val[1]);
$select->joinleft($key, $val[0], $val[1]);
}
}
//echo $select."<br/>";
//echo $select;exit;
$result = $this->db->fetchAll($select);
foreach ($result as $key => $value) {
foreach ($value as $key2 => $value2) {
$result[$key][$key2] = $this->convert2utf8($value2);
}
}
return $result;
}
