如果沒有安裝pear請看我博客中pear安裝一文。
確定pear安裝成功後，就可以安裝PHPUnit了
這是一個非常簡單而愉快的事情
官方文檔：http://www.phpunit.de/manual/3.0/en/installation.html
1）進入php安裝目錄
2） The PEAR channel (pear.phpunit.de) that is used to distribute PHPUnit needs to be registered with the local PEAR environment:
執行：pear channel-discover pear.phpunit.de
3） This has to be done only once. Now the PEAR Installer can be used to install packages from the PHPUnit channel:
執行：pear install phpunit/PHPUnit
然後就完成了
