请教Fatal error: Class 'COM' not found in
请问Fatal error: Class 'COM' not found in
我在做连接access库的时候用到adodb-ado.inc.php
但是在使用的时候报
Fatal error: Class 'COM' not found in 这个错误,是因为php.ini里面什么东西没有开吗?
------解决方案--------------------
应该是WINDOWS里的COM组件没有装好吧!
你用的是IIS么!
------解决方案--------------------
DCOM 服务器的名字,组件在此服务器上被取用。如果是 NULL,则假定是 localhost。想要允许 DCOM,必须将 php.ini 中的 com.allow_dcom 设为 TRUE。

在 Unix 下运行 PHP 而想访问 Windows 中的 MS Access,那需要 Unix ODBC 驱动程序:
1.根据 MySQL 的说明在你的平台上安装 MySQL。可以从 www.mysql.com 得到最新版(从离你最近的镜像站点下载!)。除了设定数据库和配置用户帐号以外不需要特殊的配置,应该在 host 字段中放一个 % 或者要用来访问 MySQL 的 Windows 机器名。记下自己的服务器名,用户名和密码。
2.从 MySQL 网站下载 MyODBC for Windows 驱动程序。最新版是 myodbc-2_50_19-win95.zip(也可以用于 NT,以及源代码)。在你的 Windows 机器中安装它。可以用此程序中包括的工具来测试其操作。
3.用控制面板中的 ODBC 管理器新建一个用户或系统 dsn,设定 dsn 名称,输入你在第一步中配置的 MySQL 数据库的主机名,用户名,密码,端口等。
4.完整安装 Access,这样可以确保得到适当的插件 ... 至少需要 ODBC 支持和连接表管理器。
5.新建一个 Access 数据库。在 Table 窗口点击右键并选择 Link Tables,或者在 File 菜单下选择 Get External Data -> Link Tables。当文件浏览窗口打开后,选择文件类型为:ODBC。接着选择 System dsn 以及在第三步建立的 dsn 的名字。再选择要连接的表,点击 OK。现在你可以在你的 MySQL 服务器中打开表并新建/删除/编辑数据了!也可以构造查询,导入/导出表到 MySQL,构造表单和报告等。
技巧:
1.可以在 Access 中构造表并导出到 MySQL 中,再把它们连接回来。这样可以使表的建立更快。
2.在 Access 中建立表时,必需定义一个基本键名来取得表的写权限。确认在把表连接到 Access 之前在 MySQL 中建立了基本键名。
3.如果在 MySQL 中修改了表,必须重新连接到 Access。打开 Tools>Add-ins>Linked table manager,找到你的 ODBC DSN,然后在这里选择要重新连接的表。也可以在这里移动 dsn 源,在点击 OK 之前选中 always prompt for new location。
