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
<?phpclass 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_;} }
