pear的安装
在cmd下，cd到php的安装目录，在命令行下输入如下命令读取
c:\php> php -r "readfile('http://pear.php.net/go-pear');" > go-pear
http://pear.php.net/go-pear,如果提示你的php过于新版，这输入如下的命令，
c:\php> php -r "readfile('http://pear.php.net/go-pear.pear')"
在输入c:\php> php go-pear命令
这里出现欢迎的页面，按 enter键继续，须提示使用HTTP代理，可以不填
HTTP proxy (http://user:[email protected]:port), or Enter for none::
接下来直接按Enter，到提示是否修改php.ini文件，Y表示修改,n则表示不修改
安装完成后，安装的程序会在php的安装目录下创建一个PEAR_ENV.reg注册文件来存储当前的环境变量，双击这个文件可以将内容导入到注册表,在命令行下运行PEAR.bar,如果出现如下则表示安装成功
