无法使用已安装的MDB2

Question

我使用以下命令安装了Pear：

sudo apt-get install php-pear

现在，Pear list给出了以下输出：

Installed packages, channel pear.php.net:
=========================================
Package          Version State
Archive_Tar      1.3.7   stable
Console_Getopt   1.3.0   stable
PEAR             1.9.4   stable
Structures_Graph 1.0.4   stable
XML_Util         1.2.1   stable

接下来，我使用以下命令安装了MDB2：pear install MDB2

downloading MDB2-2.4.1.tgz ...
Starting to download MDB2-2.4.1.tgz (119,790 bytes)
..........................done: 119,790 bytes
install ok: channel://pear.php.net/MDB2-2.4.1
MDB2: Optional feature fbsql available (Frontbase SQL driver for MDB2)
MDB2: Optional feature ibase available (Interbase/Firebird driver for MDB2)
MDB2: Optional feature mysql available (MySQL driver for MDB2)
MDB2: Optional feature mysqli available (MySQLi driver for MDB2)
MDB2: Optional feature mssql available (MS SQL Server driver for MDB2)
MDB2: Optional feature oci8 available (Oracle driver for MDB2)
MDB2: Optional feature pgsql available (PostgreSQL driver for MDB2)
MDB2: Optional feature querysim available (Querysim driver for MDB2)
MDB2: Optional feature sqlite available (SQLite2 driver for MDB2)
MDB2: To install optional features use "pear install pear/MDB2#featurename"

然后我使用require_once('MDB2.php')在我的一个程序中包含了MDB2.php，但是在运行时我得到了以下错误：

Warning: require_once(MDB2.php) [function.require-once]: failed to open stream: No such file or directory in /opt/lampp/htdocs/xampp/php/php_crash/phptomysql/connect.php on line 80

Fatal error: require_once() [function.require]: Failed opening required 'MDB2.php' (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/xampp/php/php_crash/phptomysql/connect.php on line 80

它清楚地表明MDB2.php is missing.i在我的当前目录中没有包含任何文件名MDB2.php。我假设它是某种全局的、随处可用的。

如何解决这个问题？我也尝试过这个：sudo pear install MDB2_Driver_$mysql

我收到了上面命令的消息：

No releases available for package "pear.php.net/MDB2_Driver_"
install failed

您需要正确设置include_path。参见the documentation。
