The weblog hosting service Blogger.com participates in the Google Data API. You can write PHP applications using Zend_Gdata_Blogger to query existing blogs, and post new entries to blogs for which you have authenticated access.
See http://code.google.com/apis/blogger/overview.html for more information about the Google Blogger API.
There are some differences regarding using the Google Data API to access blogs that are hosted on the current version of Blogger, versus blogs that are hosted on the version of Blogger that is currently in Beta. The most significant differences are related to authentication. See the table below:
表 14.1. Differences between current Blogger service and Blogger beta service
| Characteristic | Current Blogger service | Beta Blogger service |
|---|---|---|
| Supports Google Data API | Yes | Yes |
| Credentials based on | Blogger.com account | Google.com account |
| Supports ClientLogin authentication | Yes | Yes |
| Supports basic HTTP authentication | Yes | No |
| Supports AuthSub authentication | No | Yes |
| Format for unauthenticated feeds | Atom 0.3 | Atom 1.0 |
| Format for authenticated feeds | Atom 1.0 | Atom 1.0 |
| Format for posting entries | Atom 1.0 | Atom 1.0 |
| Supports query parameters | No | Yes |
Use the setBlogName() method to specify the name of
a blog. This is the name that appears in a blogspot URL,
for example:
http://blogname.blogspot.com.
You can also specify the name of the blog when you request
a feed.
<?php
$gdataBlog = new Zend_Gdata_Blogger();
// One way to get a feed for a blog...
$feed = $gdataBlog->getBloggerFeed('blogname');
// Another way to get a feed for a blog...
$gdataBlog->setBlogName('blogname');
$feed = $gdataBlog->getBloggerFeed();
?>
See the documentation for Zend_Feed for more information on how to use this object.
The setPublishedMin() and setPublishedMax()
methods allow you to specify bounds on the entry date.
If you specify a value for publishedMin,
no entries that were published earlier than the date
you specify are included in the feed. Likewise
no entries published after the date specified by
publishedMax are included.
The entries in the feed are ordered by the <updated>
element, with the most recent entry appearing first in the feed.

You can use the post() method to post entries
to your blog.
To post entries, you must be using an authenticated
Zend_Http_Client that you created using the Zend_Gdata_AuthSub
or Zend_Gdata_ClientLogin classes.
<?php
$gdataBlog = new Zend_Gdata_Blogger($authenticatedHttpClient);
$gdataBlog->setBlogName('myblog');

$xml = new SimpleXMLElement($xmlString);
$response = $gdataBlog->post($xml->asXML());

You can get a feed that names the blogs for your currently
authenticated account using the getBloggerListFeed()
method.
<?php $gdataBlog = new Zend_Gdata_Blogger($authenticatedHttpClient); $myBlogs = $gdataBlog->getBloggerListFeed(); ?>
