PHP5: July 2004 Last PHP4: Aug 2008

DEVELOPERS, LET’S MEET OUR FRAMEWORKS!

CAKEPHPWHO LOVES YA, BABY?

CAKEPHPINTRODUCTION

• “Simple is Good”

• Mental “point and click” in applications

• Lays out an example structure for you

• Works for you on two levels - websites and cli

• bake puts the “rapid” in RAD

CAKEPHPWHAT’S IN THE BOX

CAKEPHPWHAT THE CRITICS SAY

• Wrappers around simple data types

• Poor/confusing documentation

CODEIGNITERSIMPLE AND SPEEDY

CODEIGNITERINTRODUCTION

• Focuses on simplicity (doesn’t get in the way)

CODEIGNITERWHAT THE CRITICS SAY

This one’s for you, Ed

A CLOSER LOOKINSTALL & DEVELOPMENT

INSTALLATIONCAKEPHP

• Load & Go

• Change configuration options

• No need to make directories, it’s all included

• Bootstrap and front controller included

In /app/config:Database connections, routing, session handling, caching options, access control

INSTALLATIONCODEIGNITER

• Dead simple

• Update configuration for your site

• Set up database connection information

• Change any autoloads you might want

Sets up controller, helper, model, view, etc directories for you

Libraries/components loaded for every connection - useful for things like validation or certain models

INSTALLATIONSOLAR

• Not quite as “beginner friendly” as CakePHP/CodeIgniter for setup

• Requires some manual setup to get the ball rolling

• Unpack the libraries in one place, make the site in another

• Create directories for site/vendor/controllers & related files

has the “Solar System”

/www/htdocs/project/vendor/App/www/htdocs/project/vendor/External/www/htdocs/project/vendor/<Controller Name>

INSTALLATIONSOLAR - BOOTSTRAP

<?phpsession_start();

//Done!return $config;?>

INSTALLATIONZEND FRAMEWORK

• Similar in setup to Solar

• A “Do It Yourself ” Framework

• Unpack the framework

• Application can be built wherever

• Make a boostrap

INSTALLATIONZEND FRAMEWORK - BOOTSTRAP
