PEAR的其他安装方法

　　如果PHP运行环境自带PEAR，则可以在PHP目录下找到PEAR.DAT文件，双击这个文件即可进行PEAR安装，方式应该类似上述安装方式。同时注意修改PHP.INI中的include_path选项即可。

PEAR命令

　　在命令行方式下，运用PEAR的相关命令可以安装自己需要的PEAR安装包。

　　pear help  列出pear的所有命令，类似于pear的命令帮助命令。

　　pear help <command>  列出某个pear命令的具体信息

　　pear help shortcuts  列出所有pear命令的简写

　　pear list-all  列出所有可安装的packages，很多，可以访问pear扩展包列表找到需要的packages，再使用pear install命令安装package。

(安装pear时，可以让其使用默认值，一直回车完。)

接着安装单元测试框架phpunit:

d:wampinphpphp5.2.5>pear channel-discover pear.phpunit.de
Adding Channel "pear.phpunit.de" succeeded
Discovery of channel "pear.phpunit.de" succeeded

d:wampinphpphp5.2.5>pear install phpunit/PHPUnit
Did not download optional dependencies: pear/Image_GraphViz， pear/Log， channel:/
/pear.symfony-project.com/YAML， use --alldeps to download automatically
phpunit/PHPUnit requires PEAR Installer (version >= 1.8.1)， installed version is
 1.6.1
phpunit/PHPUnit can optionally use package "pear/Image_GraphViz" (version >= 1.2

phpunit/PHPUnit can optionally use PHP extension "soap"
phpunit/PHPUnit can optionally use PHP extension "xdebug" (version >= 2.0.5)
No valid packages found
install failed
(安装phpunit失败，此时通过pear upgrade pear更新pear后继续安装)
