一、从官网下载go-pear.phar 文件，地址http://pear.php.net/go-pear.phar
将下载好的文件go-pear.phar 放到PHP安装目录下，dos 命令下进入PHP安装目录 运行 php go-pear.phar，遇到提问选项，全部回车按默认选择。如果在一分钟内未按下回车键，则会提示错误然后退出。这时只要重新执行go-pear.bat即可。
如果运行成功，会如图所示：
安装完毕后，会在PHP安装目录下，生成一个pear_env.arg的注册表文件，双击该文件，将信息添加入注册表即可。
安装Mail插件：D:mvamphp5> pear install mail
安装MDB2插件：D:mvamphp5> pear install MDB2
安装PHPUnit插件：
D:mvamphp5> pear config-set auto_discover 1
D:mvamphp5>pear install pear.phpunit.de/PHPUnit
如图：
把phpunit加入环境变量，然后 phpunit --help
可以看到全部用法，如下:
D:mvamphp5>phpunit --help

如图：
二、安装包的方法:
在PHP目录下,用命令行方式执行pear install –a Auth 就会在PHPPEAR 目录下建立AUTH目录，目录中包含文件包。-a选项表明安装Auth包所依赖的所有其他包。
