What we’ll discuss today

• Why we chose PHP over other web technologies• Getting started with PHP • A road map of how to build your PHP skills• Showing what Zend software you need at

different stages

• Strategy and big picture, not a detailed technical tutorial (save that for another day)


Why we chose PHP over .NET

• .NET would lock us in to Wintel servers Costs of hardware Added complexity to administer Middleware

• PHP runs completely on your good old “i” Uses IBM’s native Apache web server Backed by IBM, shipped with v5r4 and beyond We CAN run PHP on Windows, but it’s our choice Connects directly to db2 database


Why we chose PHP over Java

• Java is a heavier solution Tends to require significant system resources and

configuration Requires sophisticated developers to create apps

• PHP is light on its feet Efficient—runs well out of the box Create useful functionality quickly; start small and grow

• Plenty of room for sophistication in larger apps Fast; low CPU load

PHP Proliferation

37% growth in PHP developers

34% of the internet runs on PHP


Reasons for PHP’s success

• Easy way to get data to Web Generates ordinary HTML, viewable in any browser

• Cross-platform: also runs on Windows, Linux, any mainstream OS

• Offers gradual path of mastery grass roots pilot project Enterprise

• Open source Managed by Zend, “the PHP company” Contributors from community and corporations


Who uses PHP?

• Yahoo, eBay, Wikipedia, Facebook

• Open source developers – 10,000+ projects

• Strong community worldwide

• 7 million+ developers

• Growing community of IBM i shops


Free, open source apps (fine on IBM i)

WordPress blog/CMS MediaWiki (Wikipedia) ZenCart e-Commerce

Sugar CRMBug Tracking/Helpdesk (Mantis400.com)


PHP on i—a short history

• 2004: i5php.net Unofficial PHP binary for “i” available online

• 2005: IBM and Zend got together

• 2006: Zend Core for i5/OS Official release with help from IBM Professional technical support from Zend

• 2007: Zend Studio: IDE/code editor • 2007: Zend Platform: performance booster and code tracer/monitor

• 2008: Zend Framework supports “i” variant of db2

• 2009: Zend Server Beta for “i” Combines the best of Core and Platform…watch for GA


Special features of PHP on i

• The included i5 Toolkit lets you: re-use your RPG logic call commands access data areas and other resources


Typical stages of PHP on i

• Grass roots Prove to yourself how well PHP works on i

• Pilot project(s) Managers see potential value; project approval

• Enterprise PHP Important projects, developed with experience


Grass roots stageGrass roots stage


Grass roots stage

• Go ahead, kick the tires! Download and install Zend Core (free)

• Includes MySQL (optional) Create a simple web page, reading/writing db2 Try open source software. Examples:

• Mantis/400, mantis400.com• WordPress, wordpress.org

Prove it to yourself before “selling” to manager


Install Zend Core

• Check the requirements/release notes http://zend.com/en/products/platform/resources

• Scroll down to Zend Core for i5/OS v2.6 i5/OS V5R4, v6.1 PASE, Qshell, recent cumulative PTF package, more

• Get FREE Zend Core for i5/OS Preloaded as licensed program or Download from http://zend.com/en/products/core/downloads

• Free account required• Look for “Zend Core for i5/OS V2.6”

Choose Windows-based installer or *SAVF

• Install on your i5 If you need MySQL, can select it, too Start Zend Core: GO ZENDCORE/ZCMENU, Option 5 then 1


Apache PHP jobs run in ZEND

• Look in Zend subsystem for Apache/PHP jobs


Zend Studio for Eclipse, IBM i Edition

• Better IDE than “Notepad”

• Free for IBM i customers http://zend.com/en/products/studio/downloads Look for “IBM i Edition”

• Lets you connect to IFS via mapped drive (“local”) or FTP or SSH (“remote”)

• Alerts you to any syntax errors or other mistakes; offers interactive debugging and code completion (similar to how green screens provide an F4 prompt)

• For good performance, your PC needs 2GB RAM


Build your skillsBuild your skills


Build your skills: Step 1

• Learn some basic HTML Try http://w3schools.com/html Tables (<table>,<tr>,<td>) useful for business data “View Source” in browser to borrow bits of HTML

• Optional: learn as needed Javascript

• Adds dynamic functionality to pages

Cascading style sheets (CSS)• Modern way to specify colors, fonts, and other attibutes of how

a site looks


Step 2: Try a simple PHP script

• PHP scripts are text files that reside in the IFS• Save script in /www/zendcore/htdocs‏/helloworld.php• Run in browser URL:

http://i5system:89/helloworld.php

<?php

// simple script to test PHP

echo “Hello, world!”;

?>


“Hello, world!” in browser

• The output of helloworld.php


Step 3: Access db2

• Example: Connect to db2 on i Select records from a db2 table Load the records in an HTML table Display the output


Connection to DB2 for i

• Need three things (OK to leave blank for default): Database name User ID Password

// Standard DB connection to DB2...$conn = ‘*LOCAL’; $name = ‘’;$pwd = ‘’;

$i5link = db2_connect($conn, $name, $pwd);if (!$i5link) echo 'Connection failed: '.db2_stmt_error().' : '.db2_stmt_errormsg();

$sql = "SELECT * from prodlib.customer";

$stmt = db2_exec($i5link,$sql)or die("Failed query:".db2_stmt_error().":".db2_stmt_errormsg());

?>


Reading data

Loop through record set

<h1> Customer list for a company</h1><TABLE BORDER="10" BORDERCOLOR="blue"><TBODY BGCOLOR="DEB887"><TR><TD>Customer Number</TD><TD>Customer Name</TD><TD>Address Line 1</TD><TD>Address Line 2</TD><TD>City</TD><TD>State</TD><TD>Zip Code</TD></TR>

<?php

echo “ <TR><TD> $row[‘CUSTNUM’] </TD><TD>$row[‘CUSTNAME’] </TD><TD>$row[‘CUSTADDR1’]</TD><TD>$row[‘CUSTADDR2’] </TD><TD>$row[‘CUSTCITY’]</TD><TD>$row[‘CUSTSTATE’] </TD><TD>$row[‘CUSTZIP’]</TD></TR>”;

}echo ‘ </table> ';db2_close($i5link);

?>


Grass roots resources

• Support: Zend Core includes one year of “silver” support

• Forums and lists forums.zend.com (look for IBM i forums) lists.nyphp.org (general PHP questions)

• Books (online and print) PHP Manual: http://php.net Zend Core for i5/OS Redbook PHP on IBM i book by Jeff Olen & Kevin Schroeder

(MC Press)

• PHP User Groups nyphp.org, liphp.org


Pilot projectPilot project


Pilot project: how to pick one

• Well defined, useful, with modest scope

• Accesses IBM i resources db2 RPG calls (optional)

• Could be a new application or extension of an existing one to the web


Our pilot project: ScoreBook.com

Added new functionality for our internal use:•Consolidated player rosters, formerly a tedious task•OpenX Ad Server (formerly PhpAdsNew)


But what is But what is EnterpriseEnterprise PHP?PHP?


Enterprise PHP is:

• Grown-up development

• Think of your mature RPG processes Consistent Reliable

• You know how to do that


Enterprise PHP in detail

• Design/development cycle Standards Security Focus on easy maintainance Reusable functionality (not just copy and paste) Procedures that ensure quality

• Deployment Need tools to help support app in live environment Predictable, consistent performance


Zend Framework

• A starting point for your advanced applications Security features Modular design

• Like the “i,” it has everything you need• You don’t have to integrate lots of pieces (HTML

template system, e-mailer, graphics, etc.)• It’s all tested for you• Free and open source


Zend Platform

Provides caching (fast!), debugging and event tracking, integration with Zend Studio (IDE)


Zend Platform: detail

Drill down to find the cause of performance lags or errors


Award winner used Zend Framework and Platform

Allied Beverage Group: Wine catalog/ordering system


Ingredients of enterprise award winning site

• Allied project won IBM/COMMON “Best Web Solution” of 2009

• For Allied, PHP brings people and resources together on the “i” db2 database provides reliable, consistent product catalog and order

data No extra servers needed Re-using RPG logic Everyone on the same team PHP is “superglue”: plans afoot to connect other systems, too

• Consistency, standards, security, reusability Zend Framework

• Speed critical for sales reps in the field (Being compared to green screen speed!) Zend Platform

• Also allows monitoring of production environment
