Agenda
• The Five Steps…
1. Understand the PHP universe
2. Understand the “stack” on IBM i
3. Install Zend Server
4. Install Zend Studio
5. Get productive!


1. Understand the PHP Universe


PHP is a Scripting Language
 PHP Hypertext Pre-Processor

 Developed initially by Rasmus Lerdorf in 1994: PHP/FI

 Zeev Suraski and Andi Gutmans Contributing since1997+
(ZEev + aNDi = Zend)
 Interpreted, not compiled

 Forgiving and intuitive code structure (Short learning
curve)
 Immediate feedback during development

 Operating model is similar to Net.Data, not as verbose

 PHP is to Java what RPG is to COBOL

Who is Zend?

• Guiding light for PHP
• Providers of stable, supported PHP distribution
• Providers of commercial tooling and support for PHP
 Zend Server

 Zend Studio


Zend and IBM

• Partnership began in 2005
• Renewed in 2008
• Zend selected by IBM to deliver PHP on IBM i
• Zend solutions pre-loaded with IBM i 6.1 and 7.1!
 Just install the LP and go!

• You can still get products and updates at Zend.com
• IBM i7.1 includes Zend Server
• Relationship expanded in 2012 to include MySQL

Why Open Source?
• Tough economic times calls for innovation
 Low cost of entry

 Applications of high quality

 Lower TCO

 Runs natively on IBM i, no need for additional hardware / OS

 You are probably already using it! (Apache Eclipse etc )
(Apache, Eclipse, etc.)

We’re not the only ones talking about Open Source…

Look what IBM is saying in February ‘09 edition!

The “Stack”
Stack
• Tested, business ready and supported distribution of PHP
• Runs Native Environment under PASE
• Home base for PHP modules like GD, PEAR, etc.
• Browser based admin console
• Accessible immediately after install
• Let’s look at the architecture of the stack
• And then installation on IBM i
• No charge LP Included with system maintenance


2. Zend Server for IBM i


What Is Zend Server?
• Production quality PHP stack
 PHP ZF, DB connectivity debugging extension
PHP, ZF connectivity, extension,
and more
• Two Editions - Free “Community Edition”

4. Install Zend Studio


Zend Studio 9 for all!

• Included for IBM i customers w/1 year support & upgrades
y pp pg
• Essential IDE for PHP on IBM i
• Syntax checker & code Completion
• JavaScript Library Support
• Debugger

Edition!)
• Install to workstation (Mac, Windows, Linux)
• Follow the prompts for licensing the product
• Zend.com with QSRLNBR to license product
• Start the IDE and begin coding PHP immediately


How do I access IFS files?
• Three methods I use
 Netserver file associations (or a mapped local drive)

• Can be sluggish
 Remote server configuration

• Best for all purposes
 WRKLNK

• Only for emergencies!


Remote Server Options

• FTP
 Familiar

 Sluggish

 Most systems support this

• SSH
 More secure

 More powerful

 Easy to setup

 Easier to setup on i6.1+


Configuring a remote server
• Start Zend Studio for IBM i
• Cli k th new connection b tt and select SSH
Click the ti button d l t
• Enter system name or IP address


Navigate to files
• Expand the tree for your system
• Navigate to the directory /www/zendsvr/htdocs
• Enter user credentials and your in!


Host side change
• CHGFTPA NAMEFMT(*PATH) CURDIR(*HOMEDIR)
LISTFMT(*UNIX)
( )
• Bounce FTP servers
 ENDTCPSVR S V (
N C SV SERVER(*FTP)
)
 STRTCPSVR SERVER(*FTP)

• If you have concerns about the host side FTP change
y g
consider the SSH method.
 V5R4 - Will need to configure and start SSH.

 i6.1+ uses STRTCPSVR command for SSHD

 See http://wiki.midrange.com/index.php/SSH

 User ID must be 8 chars or less. (Sorry, IBM restriction)

5. Get Productive!

Hello World


Sample Script – Hello World
• Obligatory program when starting out
• Confirms correct setup of PHP
• Sample code: (Shortest PHP Macro around!)
• Save script in IFS /www/zendsvr/htdocs/helloworld php
/www/zendsvr/htdocs/helloworld.php
• Browser URL: http://ibmisystem:10088/helloworld.php

<?php

echo “Hello World”;

?>


Open Source Toolkit
•Collaboration with IBM and Zend
•Built on ILE RPG Stored Procedures & pure PHP
RPG,
•Up to 10 times faster
•Object Oriented, but not too much!
Oriented
•Old toolkit not going away, but support may be

Connection to DB2 for i
• Need three things:
 System
y Note: If your data sets have *PUBLIC
PUBLIC
 User ID access, no user or password is required
 Password

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

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

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

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

?>
