With the introduction of Zend Framework 1.10,
handling of retrieving Authors and Contributors was changed, introducing
a break in backwards compatibility. This change was an effort to harmonise
the treatment of such data across the RSS and Atom classes of the component
and enable the return of Author and Contributor data in more accessible,
usable and detailed form. It also rectifies an error in that it was assumed
any author element referred to a name. In RSS this is incorrect as an
author element is actually only required to provide an email address.
In addition, the original implementation applied its RSS limits to Atom
feeds significantly reducing the usefulness of the parser with that format.
The change means that methods like
getContributors no longer return a simple array
of strings parsed from the relevant RSS and Atom elements. Instead, the return
value is an
ArrayObject subclass called
Zend_Feed_Reader_Collection_Author which simulates
an iterable multidimensional array of Authors. Each member of this object
will be a simple array with three potential keys (as the source data permits).
These include: name, email and uri.
The original behaviour of such methods would have returned a simple array of strings, each string attempting to present a single name, but in reality this was unreliable since there is no rule governing the format of RSS Author strings.
The simplest method of simulating the original behaviour of these
methods is to use the
getValues() which also returns a simple array of strings
representing the "most relevant data", for authors presumed to be their name.
Each value in the resulting array is derived from the "name" value
attached to each Author (if present). In most cases this simple change is
easy to apply as demonstrated below.
/** * Before 1.10 */ $feed = Zend_Feed_Reader::import('http://example.com/feed'); $authors = $feed->getAuthors(); /** * With 1.10 */ $feed = Zend_Feed_Reader::import('http://example.com/feed'); $authors = $feed->getAuthors()->getValues();
