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：

　　 <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; } /** * 向表中插入数据 * array $adata 数据 * string $table 表名 * int $insterid 是否需要返回插入ID * @return true or false or int */ // @bianding 2013.11.04 更改了pdo中mssql.php的lastInsertId()函数 // @bianding 2013.11.04 经测试 mssql.php中的lastInsertId()函数中的SELECT两种方式都行 function SaveData($adata, $table, $insterid = 0, $aLog = false) { //$this->db = &$this->getAdapter(); foreach ($adata as $key => $value) { $adata[$key] = $this->convert2gbk($value); } if ($this->db->insert($table, $adata)) { //var_dump($this->db->getProfiler()); $insertedID = $this->db->lastInsertId(); if ($insterid) { return $insertedID; } else { return TRUE; } } else { return false; } } /** * 删除表中数据 * * @param string $table 表名 * @param string $where id =.$id 条件 * @return true or false */ function DelData($table, $where, $aLog = false) { //$this->db = & $this->getAdapter(); if ($this->db->delete($table, $where)) { return TRUE; } else { return FALSE; } } /** * 更新表中数据 * * @param string $table * @param array $adata * @param string $where id =.$id * @return true or false */ function UpdateData($table, $adata, $cond, $aLog = false) { //$this->db = & $this->getAdapter(); foreach ($adata as $key => $value) { $adata[$key] = $this->convert2gbk($value); } if ($this->db->update($table, $adata, $cond)) { return TRUE; } else { return false; } } public function clearTable($table) { //$this->db = &$this->getAdapter(); $result = $this->db->query(TRUNCATE TABLE . $table); } public function executeSql($strSql) { //$this->db = &$this->getAdapter(); $result = $this->db->query($strSql); } function convert2utf8($string) { $config = $this->getCfg(); $pdoType = $config->db->config->pdoType; if($pdoType == dblib){ return iconv(gbk,utf-8,$string); }elseif($pdoType == sqlsrv){ //$encode = mb_detect_encoding($string, array(UTF-8,GB2312,GBK,BIG5)); //echo $encode; return mb_convert_encoding($string,UTF-8,UTF-8); //return $string; } } function convert2gbk($string) { $config = $this->getCfg(); $pdoType = $config->db->config->pdoType; if($pdoType == dblib){ return iconv(utf-8,gbk,$string); }elseif($pdoType == sqlsrv){ //$encode = mb_detect_encoding($string, array(UTF-8,GB2312,GBK,BIG5)); //echo $encode; return mb_convert_encoding($string,UTF-8,UTF-8); //return $string; } } protected function &getCfg() { if ($this->cfg_ === null) { $registry = Zend_Registry::getInstance(); $this->cfg_ = $registry->get(web_config); } return $this->cfg_; } }
