越来越多的企业使用PHP+MYSQL搭建网站，究竟PHP有什么好，为什么要选择用PHP? 1. 跨平台，性能优越，跟Linux/Unix结合别跟Windows结合性能强45%，并且和很多免费的平台结合非常省钱，比如LAMP (Linux/Apache/Mysql/PHP)或者FAMP(FreeBSD/Apache/Mysql/PHP)结合，或者数据应用够大可以考虑换 PostgreSQL或者Oracle，支持N种数据库。（N >= 10） 2. 语法简单，如果有学习C和Perl的很容易上手，并且跟ASP有部分类似。有成熟的开发工具，比如NuPHPed，或者Zend Studio等等，再Linux平台下可以使用Eclipse等等。 3. 目前主流技术都支持，比如WebService、Ajax、XML等等，足够应用。 4. 有比较完整的支持，比如使用ADODB或者PEAR::DB做数据库抽象层，用Smarty或者smart template做模板层，如果是PHP 5.1的话，还能够使用PDO（PHP Data Object）来访问数据库。 5. 有很成熟的框架，比支持MVC的框架：phpMVC，支持类似ASP.net的事件驱动的框架：Prado，支持类似Ruby On Rails的快速开发的框架：Cake等等，足够满足你的应用需求。 PHP 6. PHP 5已经有成熟的面向对象体系

作者： iamlaosong 通过VBA连接Oracle数据库查询数据，一般有两种OleDB连接驱动方法，一种是用微软的驱动，另一种用Oracle驱动，Provider需要根据实际情况修改。这儿对我使用的环境做个记录。 1、Microsoft公司提供的OleDB驱动MSDAORA，据说只支持32位系统，我在32位系统下使用没有问题，其连接字符串如下： connectionString="Provider=MSDAORA;Data Source=dataSource;User Id=userid;Password=password;" 或 connectionString="Provider=MSDAORA.1;Data Source=dataSource;User Id=userid;Password=password;" 其中MSDAORA.1是驱动的名称，“.1”据说是版本号，是COM的命名规则的一个约定格式，可以不写；dataSource是Oracle客户端配置的服务名，就是tnsnames.ora中配置的名称。驱动程序msdaora.dll放在C:\Program Files\Common Files\System\Ole DB文件夹下面。实际例子： Set cnn = CreateObject("ADODB.Connection") Set rst =
