ZendFramework框架实现连接两个或多个数据库的方法

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：

 
    PDO_MSSQL
  
      localhost
      1433
      sa
      123456
      edudb
      sqlsrv
    
  
  
  
    PDO_MSSQL
      
      localhost
      1433
      sa
      123456
      test
      sqlsrv
    
  

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

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 $select."
";
    if ($pagesize) {
      $select->limit($pagesize, $offset);
    }
    //echo $select."
";
    if (is_array($order)) {
      foreach ($order as $value) {
 $select->order($value);
      }
    } else {

    }
    //echo $select."
";
    $select->from($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."
";
 return $result;
      }
    } else {
      if ($count) {
 $result = $this->db->fetchOne($select);
 //echo $select."
";
 return $result;
      }
    }
    if (is_array($join)) {
      foreach ($join as $key => $val) {

      }
    }

 $result[$key][$key2] = $this->convert2utf8($value2);
      }
    }
    return $result;
  }
