使用ZendFramework框架怎么连接多个数据库？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
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) {

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']));
}
}
}

return $result;

//echo $select."<br/>";
return $result;
}
}
if (is_array($join)) {

//$select->join($key, $val[0], $val[1]);
$select->joinleft($key, $val[0], $val[1]);
}
}
//echo $select."<br/>";
//echo $select;exit;
