ABOUT ME PHP and Drupal Web Application Developer 5+ years
Orange County PHP (OCPHP) Organizer : 7 years Orange County Drupal (OC Drupal) CoOrganizer : 2 years Grew up in San Gabriel Valley area (Azusa) Lives in Orange County

ABOUT PRESENTATION A Brief History Very Quick Overview Basics Beyond
Basics Leveraging the community Frameworks for your content Resources Questions PHP is pretty broad so not very technical

PHP A BRIEF HISTORY

PAST Rasmus Lerdorf conceived PHP in 1994 Personal Home Page
Tools (PHP Tools) A simple parser to generate dynamic content through variables in HTML Zeev Suraski and Andi Gutmans from Tel Aviv get Involved Added thread safety mechanism and more advanced tag-parsing mechanism Known as the Zend Engine PHP 4.0 released in May 2000

TODAY PHP 5.x is released Many development enhancements incorporated including
OOP, XML, and Database connectivity Core developers continue to add features Zeev Suraski and Andi Gutmans formed Zend to target the Enterprise Zend Framework Zend Server Zend Studio

PHP BASICS

BASICS Runs on apache nginx windows Connects with mysql mongodb
postgres Tests with Simpletest PHPUnit Common Setups

BASICS Mix PHP syntax with your HTML Good but ....
separate your PHP, CSS, and XHTML in individual ﬁles <html> <head> <title>PHP Test</title> <style> p { color: red; } </style> </head> <body> <?php echo '<p>Hello World</p>'; ?> </body> </html> Simple Example

BASICS Separate code into ﬁles Manage your code

PHP BEYOND BASICS

BEYOND BASICS do OOP instead (if possible) If you do
procedural function get_posts() { // Build database query $sql = 'select * from post'; // Execute query and return all rows return execute_query($sql); } OOP class blog { public function get(){ // Build database query $sql = 'select * from post'; // Execute query and return all rows return execute_query($sql); } }

BEYOND BASICS Debugging Maintainability Readability of Code OOP Beneﬁts Procedural
can be quicker to crank out but OOP provides Many frameworks are heavy on OOP

BEYOND BASICS What are they? Well-thought out solutions to programming
problems Design Patterns Leverage Design Patterns in OOP code

BEYOND BASICS Design Patterns : Decorator Pattern class HtmlEntitiesDecorator extends
ServiceClientDecorator { public function getData() { return htmlentities($this->serviceClient- >getData()); } } abstract class ServiceClientDecorator implements ServiceClient { protected $serviceClient; public function __construct(ServiceClient $serviceClient) { $this->serviceClient = $serviceClient; } } $client = new MyWebServiceClient(); // Add our decorators $client = new HtmlEntititesDecorator($client); $client = new ParagraphDecorator($client); // Later in your code, and possibly in multiple places print $client->getData();

BEYOND BASICS Many new frameworks use it (eg. Laravel) Easy
way to include dependencies Composer A new Dependency Manager going forward

BEYOND BASICS Ways Frameworks can work with one another Propose
standards recommendations (PSR) Voting members from various top frameworks Standards PHP Framework Interoperability Group (PHP FIG)

BEYOND BASICS PSR-0 Standards : Accepted Autloader interoperability How to
structure qualiﬁed namespaces so framework can easily autoload classes PSR-1 Basic coding standards High level basics of coding standards to complement a frameworks own standard PSR-2 Basic coding style High level coding styles (formatting) that extends PS-1. PSR-3 Common library logging interface Allow libraries to receive a logging interface object and write the log in a simple and universal way

GOING BEYOND JUST SYNTAX ....

DON’T REINVENT THE WHEEL leverage the community to get your
content to the user

FRAMEWORKS Zend Framework Enterprise Level Framework More involved framework /
Heavy OOP Great documentation and examples Zend (the original PHP people) lead development Provides an MVC base structure (Custom applications)

FRAMEWORKS CodeIgniter Easy to use Framework Great documentation Company leads
direction with community involvement (also a negative) Many plugins available Provides an MVC base structure (Custom applications)

FRAMEWORKS Symfony Easy to learn framework Decoupled (components can be
used seperately, eg, use its serial component) Great documentation and examples Company and community lead development Provides an MVC base structure (Custom applications)

FRAMEWORKS Laravel Easy to use framework Good documentation support A
fairly new framework that takes advantage of PHP’s latest Company and community lead developer (currently hot in community) Provides an MVC base structure (Custom applications) Uses pieces of Symfony

FRAMEWORKS Drupal Easy to use CMS (can also be used
as Framework) Incredible community support Great documentation, examples, and countless modules Core (mostly from Acquia) and community leads its development Provides and out of the box CMS Upcoming Drupal 8 will use pieces of Symfony (other option, Wordpress)

TEMPLATING Twig Popular template engine Good documentation and API Friendly
syntax than designer having to know PHP Can be plugged into other Frameworks Will be used at the Drupal 8 template engine (other option, Smarty)

WHY PHP?

DEVELOPMENT Many hobbyist (easy syntax to learn - to a
fault) Demand is very high Abundant developers 23,151,357 websites using PHP.

WHY PHP Powers some top topic content websites Drupal Drupal
Zend Framework
