2. Welcome
• Today I’ll be introducing you to the Zend
Framework
What it is
Why we’re doing it
How to use it
Where it’s going
How to be a part of it

3. Getting Started
• Zend Framework is..
A modular collection of PHP classes based on PHP 5 to
simplify common tasks
A starting point for your applications
A demonstration of PHP 5 best practices
A smaller component of the PHP Collaboration Project
• Zend Framework isn’t…
A free-reign open source project
A religion

4. Goals of the Framework
• Zend Framework strives to be fundamentally….
An industry-leading framework for PHP application
development
A partnership between many companies already
experienced in PHP Framework development
• Zend Framework strives to be technically…
A source of high-quality, PHP 5 / E_STRICT compatible
application components
Completely PHP 5 powered, requiring as few external PHP
extensions as necessary
A minimal object hierarchy to achieve the necessary goals
Modular design allowing developers to use the framework at
will, as they see fit.

5. Why Yet another Framework?
• Keep PHP competitive with other technologies
.NET, Java, etc.
• Provide “clean” IP to enable commercial use
Real companies can’t just “borrow” code from the
Internet without clear licensing
• “Extreme Simplicity”: It may not be simple
•
technically, but using it should be.
Take full advantage of PHP 5

6. The Framework License
• Zend Framework is licensed using a PHP/BSD
style license
Anyone can use it, for anything, no strings attached –
period.
• Along with the license of the framework itself,
contributors must sign a Contributor License
Agreement (CLA)

7. There’s no such thing as a free…
• Why spend so much time and effort on
something, just to give it away?
Yes, we’re still interested in making money
• For the continued success of PHP it must be a
collaboration beyond OSS hackers
Through the PHP Collaboration project, and projects
like Zend Framework, we can leverage the knowledge
of some of the best in the industry in the benefit of PHP
as a whole
As you might expect, Zend benefits with PHP

8. We eat our own dog food
• Zend Framework is more than unit-tested, it is
used in real-life production environments
Gives us the ability to test performance, ease of use,
etc. in a practical environment
Zend and its partners are already using the preview
release of the Framework to speed development of
their applications
Both the Framework homepage (framework.zend.com)
and our new Developer’s Zone (devzone.zend.com)
use the preview release of Framework as their
foundation.

9. The grail: Extreme Simplicity
• Many of PHP 5’s most exciting new technologies
are really simple to use:
Simple XML
SOAP
Tidy
• While the underlying technologies may be
extremely complex, the end-user APIs are
reduced to an extremely simple interface
Dec 4, 2013

10. Getting the Grail
• To achieve the grail of extreme simplicity
“Simple things should be simple, complex things should
be possible”
• Use-at-will architecture
You shouldn’t be forced into buying the whole pizza
just for a slice
Use individual components (controller/model) without
being forced to use everything (your own
template/view)
• Configuration-less
The framework should be plug-and-go, no
configuration files necessary

12. Completely PHP-5 focused
•
•
•
•
•
•
Requires PHP 5.0.4 or later for near future
Takes full advantage of the PHP exception model
Constants are all at the class-level
No functions in global namespace
ZE2 / SPL technologies fully utilized where it
makes sense
Black magic __magic() functions used very
sparsely

13. Preview Release
• PR 1.2 is the latest preview release of the
Framework including many immediately useful
tools such as:
A basic MVC framework for application design
A PDO-based database layer
Feed (RSS, Atom) ingestion and manipulation
An HTTP client
Input data filtering
Json support for AJAX
PDF generation and manipulation
RPC / Web service support
And more!

14. Getting Zend Framework
• You can either get the framework preview
release or check out the latest repository version
• Preview Release: http://framework.zend.com/
• Repository:
$ svn checkout http://framework.zend.com/svn/framework/trunk

15. Installing Zend Framework
• Installing the framework is very easy, just modify
your include_path to include the library/
directory
From php.ini:
……
include_path=“.:/usr/local/lib/php:/usr/local/lib/ZendFramework”
……
From .htaccess
……
php_value include_path “.:/usr/local/lib/php:/usr/local/lib/ZendFramework”
……

16. MVC Pattern
• MVC, or Model View Controller pattern is a
•
•
powerful technique for developing user
interfaces
Originally was conceived for client-side GUI
applications and adopted to the web
Zend Framework provides a simplistic MVC
model
Dec 4, 2013
# 16
17. Example Controller
• Note: indexAction() is declared abstract in
Zend_Controller_Action, and therefore must be
defined in any Action/Page controller
Dec 4, 2013
# 17
18. Passing Parameters
• Beyond $_GET/$_POST you can also pass
parameters to a specific controller action by
appending them to the URL:
http://localhost/foo/dosomething/param1/value1/param2/value2
• Parameters can be accessed from within the
action by name
$this->_getParam(<key> [, <default value>]);
$this->_getAllParams();

19. Dealing with 404s
• 404 errors are no longer the responsibility of
•
Apache per-se, and are more likely to result in a
‘Class not found’ / ‘Method not found’ exception
To deal with these Zend Framework provides two
methods
In the event of a controller not found, the
IndexController::noRoute() method will be called
instead
In the event a controller action is not defined, it is the
responsibility of the controller to implement safeguards
(i.e. __call() which traps bad action calls)

20. Chaining Controllers
• Controllers can be chained together to either
break business logic out into components, or to
otherwise redirect the user
$this->_forward(<controller_name> [, <parameters>])
Parameters are a series of key/value pairs
Controller Chaining does not occur until the current
action is complete, to immediately forward you must
return from the current action after calling _forward()
• Forwarding does not cause a refresh on the
client, to physically refresh the browser
$this->_redirect(<url>);

21. Final thoughts on MVC
• Although the pattern dictates three individual
•
class types, they are as conceptual as functional
For instance a “model” or “view” isn’t absolutely
necessary to gain most of the benefit of MVC
You can always perform queries from a controller
You can always print output from a controller
• Although not necessary, they are never the less
recommended

23. Zend_InputFilter
• Security is a primary concern in Zend Framework
• As such, we provide facilities to clean and
manage untrusted data in your applications via
Zend_InputFilter and Zend_Filter
Provides a number of methods for filtering data against
many common data types (digits, alphanumeric,
alpha, phone, etc.)
Dec 4, 2013
# 23
24. Using Zend_InputFilter
• With Input Filter you can both test data types and
retrieve filtered data easily
• Note, by default the source of the data and all of
it’s references are destroyed when filtered

25. Zend_Mail
• Simplifies building and sending e-mail
• Supports MIME types and multipart e-mail
• Supports multiple transports and persistent
connections automatically
• Supports large file attachments via the streams
API improving performance

27. Zend_Search
• PHP 5 implementation of the popular Lucene
search engine from the Java world.
• Simplified API
• Requires no special PHP extensions
• Fully compatible with the binary index format of
Java Lucene 1.4 and above
Dec 4, 2013
# 27
28. Zend_Search Features
• Ranked Searching
Best results always first
• Many Query types: phrase, wildcard, proximity
• Search by field (Author, title, body, etc.)
• Robust, and simple API
One-method intelligent searches against indexes, or
complex OO queries if desired
Index multiple document types, with different field
requirements
Dec 4, 2013
# 28
29. Using Zend_Search
• Using Zend Search is very easy
• The search engine also boasts a parser for google-like searching: zend php -java
Dec 4, 2013
# 29
31. Cool things about Zend_Search
• The Lucene search engine allows you to index
multiple document types in a single index, each
with different index fields
Index Individual documents with different searchable
criterion
I.e. Index code samples by functions used, while
articles by title, author, and keywords in the same
index
• Because it is 100% compatible with Lucene 1.4+,
it is compatible with all pre-created index files
