require 'xmlrpc/client'
#建立server

	server=XMLRPC::Client.new2("http://www.jiangmiao.org/blog/xmlrpc.php")
	server.call("wp.getUsersBlogs","admin","blog密码")

	puts $!.message
end

运行后返回我的blog信息

blogid  1
blogName        江淼的Blog
xmlrpc  http://www.jiangmiao.org/blog/xmlrpc.php
url     http://www.jiangmiao.org/blog/
isAdmin true

就是这么简单:)

#Ruby
class foo
def bar
@hello = 'Hello Ruby'
 puts @hello
puts 1<2
puts 2>1
end
end

<?php
//php
class foo
{
function bar()
{
echo "Hello php";
}
}

只是在线编辑器不够方便，按TAB没法自动缩进。
