Introduction to PHP

© All rights reserved. Zend Technologies, Inc. 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 PHP is to Java what RPG is to COBOL

• Production quality PHP stack  PHP, ZF, DB connectivity, debugging extension, and more • Three Editions – No charge “Basic Edition” provided by IBM & Full Professional and Enterprise commercial edition  All are production ready • Application monitoring and diagnostics (integrated with Zend Studio) • Multi-level performance enhancement capabilities • Software updates and security hot fixes • Easy and quick installation • Zend Framework Integration

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/zendsvr6/htdocs /helloworld.php • Browser URL: http://ibmisystem:10080/helloworld.php

Open Source Toolkit

•Set of classes that access IBM i native artifacts •All Program Objects RPG, COBOL, CL, etc. •Others Command processor Data Queue’s Spooled File More… •Access naturally from PHP code. No SP’s required •Easy to use

•Series of classes that “wrap” the IBM project •All PHP but Object Oriented…(wait, there’s more!) •Zend built the PHP wrapper •No OO training required to use them!!!

•Sam Pinkhasov, Zend

XML Service

•IBM has open sourced XMLService. •First Open Source project on IBM i. (that I know of…) •Made up of RPG, CL and DB2 stored procedures (SQL)

•Tony Cairns, IBM Rochester

•Cross platform •Language agnostic •Basic plumbing for all open source languages

•Intercepts existing i5 function requests •Written in pure PHP •Passes them on to OO PHP which then… •Passes on to XML Service

•Class where all wrapper functions start Yes, this is OO but not too bad… Look at it and poke around, It’s OK! This is why we need the path set correctly

•Need to set the extension and instantiate the object Singleton pattern Try & Catch Can put this in your own include

•Set parameters based on function Call program V I C L a n o e r i I m  n t Output results m / g e n t v n a O h a t m e l

• AddParameterInt32($io, $comment, $varName, $value, $dimension) • AddParameterInt64($io, $comment, $varName, $value, $dimension) • AddParameterUInt32($io, $comment, $varName, $value, $dimension) • AddParameterUInt64($io, $comment, $varName, $value, $dimension) • AddParameterFloat ($io, $comment, $varName, $value, $dimension) • AddParameterReal($io, $comment, $varName, $value, $dimension) • AddParameterPackdec($io, $length, $scale, $comment, $varName, $value, $dimension) • AddParameterZoned($io, $length, $scale, $comment, $varName, $value, $dimension) • AddParameterBin($io, $size, $comment, $varName, $value, $dimension) • AddDataStruct($array, $parameters, $name=‘struct_name’, $dim, $by, $isArray, $labelLen)

Stored Procedure - Array

Data elements are nice, but… Sometimes you need a little more… How about an array of information?

Stored Procedure – Record Set

Command processing & *libl

•$conn->CLCommand(‘my command’); •$conn->CLInteractiveCommand(‘DSP… command’); •$conn->CLCommandWithOutput(‘RTV… command’);

•Command processing Call CL command directly from toolkit Retrieve response from command call •Example DSPLIBL CHGLIBL DSPLIBL Useful for managing access to resource • Files & Programs from RPG

Pricing Example

•RPG is black box, callable from nearly anywhere •PHP has function to contain RPG call •Routine to spin through line call for each quantity

•Setup session for user-RPG program dedication

Miscellaneous Toolkit Points

•Toolkit.ini setting Debug = TRUE •Turns on DebugOutput file debugLogFile = "/usr/local/zendsvr/share/ToolkitApi/debug.log“ •Many other directive settings here

•IPC •Use session ID, for example • $PHPToolkitObj->setToolkitServiceParams ( array ('InternalKey' => "/tmp/$user" ) );
