安装PHP PEAR和MDB2后警告/致命错误要求（MDB2.php）

Question

我已经在我的本地主机上成功安装了PEAR和MDB2。 但是，当我试图运行由MDB2给出的示例代码时，我得到错误（在附图中）

也安装后多次重新启动Wamp服务器。

错误和警告

Warning: require(MDB2.php) : failed to open stream: No such file or directory in E:\wamp\www\pear_project\examples\example_php5.php on line 8

Fatal error: require() : Failed opening required 'MDB2.php' (include_path='.;C:\php\pear') in E:\wamp\www\pear_project\examples\example_php5.php on line 8

php.ini中是默认期间PEAR安装通过去梨修改。

Answer 1

我已经解决了这个问题。 卸载旧的WAMP并删除剩下的wamp文件夹。 然后新鲜安装WAMP和PEAR。 使用PHP文件夹路径修改环境变量。

有一个在Ë另外的php.ini：\ WAMP \ BIN \ apache的\ Apache2.4.4 \ BIN

修改php.ini与同包括路径

include_path=".;E:\wamp\bin\php\php5.4.12\pear"

安装数据库软件包MDB2 ，

并重新启动服务器。

您应该重新启动您的Web服务器时更改为php.ini做，否则将不能生效。

您当前的配置在寻找：include_path='.;C:\php\pear' 然而，系统中安装了此目录中：E:\wamp\bin\php\php5.4.12\pear

重新启动wampp安装完毕后，应该开始工作。
