This article is meant to followup sfZendPlugin where we learn a newer way of obtaining the Zend Framework. In this tutorial weÂ’re going to delve into the Lucene index. Zend Search Lucene relies on building a Lucene index. This is a directory that contains files that can be indexed and queried by Lucene or other ports. In our example weÂ’ll be creating a search for user profiles.

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.

After getting a little impatient looking at PHP code from however many projects and seeing the typical approach of making input filtering, sql and output escaping the responsibility of the human error-prone developer, I'm now making it standard practice on any of the projects I run to dump this sorry mess. And it is usually a mess. The fact is you cannot trust a developer to manually secure source code - it's like God relaying the Ten Commandments to Moses. No matter how many burning bushes, prophets, unnatural disasters, signs and miracles you use to emphasis those ten simple rules, you can still wager there will be a bunch of folk breaking them (including myself!) left, right and centre. It's human nature to err. It's my nature to make the verb "err" redundant.

Zend_Service_Amazon is a simple API for using Amazon web services. Zend_Service_Amazon has two APIs: a more traditional one that follows Amazon's own API, and a simpler "Query API" for constructing even complex search queries easily. Zend_Service_Amazon enables developers to retrieve information appearing throughout Amazon.com web sites directly through the Amazon Web Services API. Examples include: Store item information, such as images, descriptions, pricing, and more; Customer and editorial reviews; Similar products and accessories; Amazon.com offers; ListMania lists.

What do you guys think of Zend_Validate? I haven't looked at Zend_Validate much, but I'm not really a fan of complex interfaces either. I like your idea to validate all that needs validated in one go, but I don't like your interface for adding validators.

A couple of weeks ago, Google jumped into the online calendar space by launching Google Calendar (um, beta). The application is chock-full of Ajaxy goodness and plenty of features, but I'm here to talk about what you can do with your calendar data behind the scenes. Using some handy tools from the Swiss Army Knife that is the Zend Framework, I'll show you how to pull data from your Google Calendar into your site. Just for kicks, I'll also throw in a caching layer to keep things fast and reduce the network traffic between your server and Google.

Zend_Service_Yahoo is a simple API for using many of the Yahoo! REST APIs. Zend_Service_Yahoo allows you to search Yahoo! Web search, Yahoo! News, Yahoo! Local, Yahoo! Images.

If you want to have your ZF aplication still working after migration from 0.2.0 to 0.6.0, you should make some changes in your code. However, it's desribed in manual, but only for Zend_Controller classes.

I, for one, am eagerly awaiting the Zend Framework. When it was first announced, I feared that it was going to be a framework highly geared towards enterprise development with tie-ins to a bunch of other Zend tools like the Zend Platform or either of the Zend Core things (Oracle or DB2/Cloudscape). What IÂ’ve heard since has relieved a bunch of that fear, and given me some hope about its development and the future of PHP. Their main goal, as many have now reported, is that of extreme simplicity. Unfortunately for those developing any software product, making it extremely simple is not an extremely simple thing - itÂ’s normally an extremely difficult thing. Trying to create an application that will be easy to install, easy to deploy, and easy to use is a very difficult thing. Especially when you have to do it quickly, you have a lot of people ready to pounce on you when you make mistakes, and the thing youÂ’re trying to make extremely simple isnÂ’t a trivial problem.

Zend_Measure provides a generic and very easy way for working with measurements. Using Zend_Measure, you can convert measurements into different units of the same type. They can be added, subtracted and compared against each other. From a given input made in the user's native language, the unit of measurement can be automatically extracted. Of course a great number of completely different units of measurement is being supported. Most of these units are of a physical nature, but there are also special measurements used, in numerics or other areas, that are only partly physical - or not at all. The following quickstart tutorial shows how units of measurement can be automatically converted.
