这篇文章主要介绍了zend框架实现支持sql server的操作方法,结合实例形式分析了zend框架的相关代码修改、配置文件设置与相关问题注意事项,需要的朋友可以参考下
本文实例讲述了zend框架实现支持sql server的操作方法。分享给大家供大家参考，具体如下：
1.修改Zend/Db/Adapter/Pdo/Abstract.PHP中的connect方法
_connection) {
return;
}
// get the dsn first,because some adapters alter the $_pdoType
$dsn = $this->_dsn();
// check for PDO extension
if (!extension_loaded('pdo')) {
/**
* [url=home.PHP?mod=space&uid=86763]@see[/url] Zend_Db_Adapter_Exception
*/
require_once 'Zend/Db/Adapter/Exception.PHP';
throw new Zend_Db_Adapter_Exception('The PDO extension is required for this adapter but the extension is not loaded');
}
// check the PDO driver is available
if (!in_array($this->_pdoType,PDO::getAvailableDrivers())) {
/**
* @see Zend_Db_Adapter_Exception
*/
require_once 'Zend/Db/Adapter/Exception.PHP';
throw new Zend_Db_Adapter_Exception('The ' . $this->_pdoType . ' driver is not currently installed');
}
// create PDO connection
$q = $this->_profiler->queryStart('connect',Zend_Db_Profiler::CONNECT);
// add the persistence flag if we find it in our config array
if (isset($this->_config['persistent']) && ($this->_config['persistent'] == true)) {
$this->_config['driver_options'][PDO::ATTR_PERSISTENT] = true;
}
try {
//print_r($this->_config);exit;
if($this->_config['pdoType']=='sqlsrv'){
$this->_connection = new PDO( "sqlsrv:Server=".$this->_config['host'].";Database = ".$this->_config['dbname'],$this->_config['username'],$this->_config['password']);
$this->_connection->setAttribute( PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION );
$this->_connection->setAttribute( PDO::sqlSRV_ATTR_ENCODING,PDO::sqlSRV_ENCODING_UTF8 );
$this->_profiler->queryEnd($q);
}elseif ($this->_config['pdoType']=='dblib') {
$this->_connection = new PDO(
$dsn,$this->_config['password'],$this->_config['driver_options']
);
$this->_profiler->queryEnd($q);
}
// set the PDO connection to perform case-folding on array keys,or not
$this->_connection->setAttribute(PDO::ATTR_CASE,$this->_caseFolding);
// always use exceptions.
$this->_connection->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
/**
* @see Zend_Db_Adapter_Exception
*/
require_once 'Zend/Db/Adapter/Exception.PHP';
throw new Zend_Db_Adapter_Exception($e->getMessage());
}
}
这里针对linux和windows提供两种连接方式。
2.mssql.PHP 中的为
_config;
// don't pass the username and password in the DSN
unset($dsn['username']);
unset($dsn['password']);
unset($dsn['driver_options']);
if (isset($dsn['port'])) {
$seperator = ':';
if (strtoupper(substr(PHP_OS,3)) === 'WIN') {
$seperator = ',';
}
$dsn['host'] .= $seperator . $dsn['port'];
unset($dsn['port']);
}
// this driver supports multiple DSN prefixes
// @see http://www.PHP.net/manual/en/ref.pdo-dblib.connection.PHP
//print_r($dsn);exit;
if (isset($dsn['pdoType'])) {
switch (strtolower($dsn['pdoType'])) {
case 'freetds':
case 'sybase':
$this->_pdoType = 'sybase';
break;
case 'mssql':
$this->_pdoType = 'mssql';
break;
case 'sqlsrv':
$this->_pdoType = 'sqlsrv';
break;
case 'dblib':
default:
$this->_pdoType = 'dblib';
break;
}
unset($dsn['pdoType']);
}
// use all remaining parts in the DSN
foreach ($dsn as $key => $val) {
$dsn[$key] = "$key=$val";
}
$dsn = $this->_pdoType . ':' . implode(';',$dsn);
// print_r($dsn);exit;
return $dsn;
}
3.ZF 的web.xml 数据库配置文件改成：
PDO_MSSQL
localhost
sa
123456
testdb
sqlsrv
期间遇到中文乱码问题
getCfg();
$pdoType = $config->db->config->pdoType;
if($pdoType == 'dblib'){
return iconv("gbk","utf-8",$string);
}elseif($pdoType == 'sqlsrv'){
return mb_convert_encoding($string,"UTF-8","auto");
}
}
function convert2gbk($string)
{
$config = $this->getCfg();
$pdoType = $config->db->config->pdoType;
if($pdoType == 'dblib'){
return iconv("utf-8","gbk","GBK","auto");
}
}
protected function &getCfg() {
if ($this->cfg_ === null) {
$registry = Zend_Registry::getInstance();
$this->cfg_ = $registry->get('web_config');
}
return $this->cfg_;
}
针对不同的类型，进行不同的处理。
