chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
4. make
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
5. make install
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
6. cp ./php.ini-dist /wherever/your/conf/files/are/php.ini

7. 修改httpd.conf
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
修改如下这一行
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
LoadModule php4_module lib/apache/libphp4.so
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
改为：
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
LoadModule php4_module /usr/lib/apache/libphp4.so
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
8. 重新启动APACHE
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
9. 测试PHP4的安装是否成功
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
创建一个test.php3内容为：
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
在浏览器中访问它，看是否有ORACLE和ORACLE8的信息。
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
如果有的话，那么就恭喜你了！
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
10. 现在开始使用ORACLE的函数吧
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
// 设置ORACLE环境变量
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
putenv("ORACLE_SID=PROD");
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
putenv("ORACLE_HOME=/usr/local/oracle/8i/u01/app/oracle/product/8.1.5");
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
// 建立连接
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
// 修改现在的user_id,password,db以适应你的配置
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
if($conn = OCILogon("user_id","password","db"))
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
{
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
// 取得数据库的信息
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
printf("%s
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
", OCIServerVersion($conn));
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
}
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
else
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
{
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
printf("Conncetion Failed");
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
}
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
?>
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
这段程序会显示出你所连接到的ORACLE的一些信息
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac

chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
12. 其它
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
如果你需要连接到远程的ORACLE服务器，你就还需要设置你的sqlnet.ora 和 tnsnames.ora 来指定远程数据库的位置。
chi na it p owe r .comnJecmGJG22UWEnXlat8aW2wac
向数据库管理员要求，拷贝一些文件放到$ORACLE_HOME/network/admin/ 目录下
