POST TO BLOGGER USING PHP AND CURL

Before you can use this script, you need a blogger acocunt.
They're free - go to http://blogger.com
You need to have a blog that you can post to.
You need to know the blogid of the blog you want to post to.
To get the blogid, go to blogger.com and log in to your blogger account.
There will be a list of blogs.
When you click on a blog name, it will go to a url like :
http://www.blogger.com/posts.g?blogID=1234567

The blogID portion is what you use for your $blog_id
- in the above example it is 1234567

To carry out other blogger tasks, refer to the Atom API Documentation for
