PEAR的其他安裝方法
如果PHP運行環境自帶PEAR，則可以在PHP目錄下找到PEAR.DAT文件，雙擊這個文件即可進行PEAR安裝，方式應該類似上述安裝方式。同時注意修改PHP.INI中的include_path選項即可。
PEAR命令
在命令行方式下，運用PEAR的相關命令可以安裝自己需要的PEAR安裝包。
pear help 列出pear的所有命令，類似于pear的命令幫助命令。
pear help <command> 列出某個pear命令的具體信息
pear help shortcuts 列出所有pear命令的簡寫
pear list-all 列出所有可安裝的packages，很多，可以訪問pear擴展包列表找到需要的packages，再使用pear install命令安裝package。
(安裝pear時，可以讓其使用默認值，一直回車完。)
接著安裝單元測試框架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
.1)
phpunit/PHPUnit can optionally use package "pear/Log"

phpunit/PHPUnit can optionally use PHP extension "soap"
phpunit/PHPUnit can optionally use PHP extension "xdebug" (version >= 2.0.5)

install failed
(安裝phpunit失敗，此時通過pear upgrade pear更新pear后繼續安裝)
