Zend Framework 1.6.2 Manual

Zend_Service_Delicious is simple API for using » del.icio.us XML and JSON web services. This component gives you read-write access to posts at del.icio.us if you provide credentials. It also allows read-only access to public data of all users.

getAllPosts();

foreach ($posts as $post) {
    echo "--\n";
    echo "Title: {$post->getTitle()}\n";
    echo "Url: {$post->getUrl()}\n";
}

Zend_Service_Delicious provides three methods for retrieving posts: getPosts(), getRecentPosts() and getAllPosts(). All of these methods return an instance of Zend_Service_Delicious_PostList, which holds all retrieved posts.

Instances of this class are returned by the getPosts(), getAllPosts(), getRecentPosts(), and getUserPosts() methods of Zend_Service_Delicious.

For easier data access this class implements the Countable, Iterator, and ArrayAccess interfaces.

getAllPosts();

// count posts
echo count($posts);

// iterate over posts
foreach ($posts as $post) {
    echo "--\n";
    echo "Title: {$post->getTitle()}\n";
    echo "Url: {$post->getUrl()}\n";
}

// get post using array access
echo $posts[0]->getTitle();

Note:

The ArrayAccess::offsetSet() and ArrayAccess::offsetUnset() methods throw exceptions in this implementation. Thus, code like unset($posts[0]); and $posts[0] = 'A'; will throw exceptions because these properties are read-only.

Post list objects have two built-in filtering capabilities. Post lists may be filtered by tags and by URL.

getAllPosts();

// Print posts having "php" and "zend" tags
foreach ($posts->withTags(array('php', 'zend')) as $post) {
    echo "Title: {$post->getTitle()}\n";
    echo "Url: {$post->getUrl()}\n";
}

getAllPosts();

// Print posts having "help" in the URL
foreach ($posts->withUrl('/help/') as $post) {
    echo "Title: {$post->getTitle()}\n";
    echo "Url: {$post->getUrl()}\n";
}

There are two ways to delete a post, by specifying the post URL or by calling the delete() method upon a post object.

deletePost('http://framework.zend.com');

// or by calling the method upon a post object
$posts = $delicious->getPosts();
$posts[0]->delete();

// another way of using deletePost()
$delicious->deletePost($posts[0]->getUrl());

To add a post you first need to call the createNewPost() method, which returns a Zend_Service_Delicious_Post object. When you edit the post, you need to save it to the del.icio.us database by calling the save() method.

createNewPost('Zend Framework', 'http://framework.zend.com')
          ->setNotes('Zend Framework Homepage')
          ->save();

// create a new post and save it  (without method call chaining)
$newPost = $delicious->createNewPost('Zend Framework', 'http://framework.zend.com');
$newPost->setNotes('Zend Framework Homepage');
$newPost->save();

The del.icio.us web API allows access to the public data of all users.

Note:

When using only these methods, a username and password combination is not required when constructing a new Zend_Service_Delicious object.

getUserFans('someUser'));

// get network of user someUser
print_r($delicious->getUserNetwork('someUser'));

// get tags of user someUser
print_r($delicious->getUserTags('someUser'));

Zend_Service_Delicious uses Zend_Rest_Client for making HTTP requests to the del.icio.us web service. To change which HTTP client Zend_Service_Delicious uses, you need to change the HTTP client of Zend_Rest_Client.

When you are making more than one request with Zend_Service_Delicious to speed your requests, it's better to configure your HTTP client to keep connections alive.

setConfig(array(
        'keepalive' => true
));

Note:

When a Zend_Service_Delicious object is constructed, the SSL transport of Zend_Rest_Client is set to 'ssl' rather than the default of 'ssl2'. This is because del.icio.us has some problems with 'ssl2', such as requests taking a long time to complete (around 2 seconds).
