Zend Studio 7.2.1 faster, more reliable

I just upgraded my copy of Zend Studio for IBM i from 7.0.2 to 7.2.1. Big improvement!

My use case: I typically use Zend Studio’s “Remote Server” facility to connect to the IBM i over FTP. With 7.2.1, FTP-based files now open and save much faster than before. In addition, the FTP connection no longer randomly disconnects the way it used to.

I recommend upgrading to 7.2.1, especially for anyone using FTP. It provides a smooth, hassle-free user experience.

Get Zend Studio here: http://www.zend.com/en/products/studio/downloads. Scroll down to the edition you need.

Note: this product is still free to users of IBM i, a nice benefit of Zend’s relationship with IBM.

A simple security measure

A reader recently asked me this security question:

If a user enters:
http://<my_ip>/<mydirectory>
instead of
http://<my_ip>/<mydirectory>/script.php

They get a listing of all scripts/files in that directory and they can then select and execute/run those scripts.

This is a real concern for us, any suggestions?

The solution is to turn off directory browsing in your Apache configuration. To do this, make sure your Apache configuration file (probably httpd.conf or .htaccess) includes this directive:

Options -Indexes

Note that this directive merely prevents people from discovering the names of your files. Users who already know your file names can still access them. But Options -Indexes provides an important layer of security, preventing mischief from casual users who might otherwise stumble onto your file names by accident or design.

See me speak about web services and Zend Framework

Join me at at Long Island PHP on June 7, 2010, where I’ll present a case study showing how I integrated Windows-based data into an IBM i-based application using SOAP with Zend Framework.

The principles are the same no matter what type of servers you use.

There will be plenty of time for questions and discussion.

Hope to see you there!

Differences Between Zend Core and Zend Server on IBM i

Zend Server for IBM i improves upon Zend Core’s older implementation of PHP in numerous ways. To make the migration easier, I’ve created a table that shows some of the settings and default file locations that have changed between Zend Core and Zend Server.

Zend Core
Zend Server
Installation folder
/usr/local/zend/core
/usr/local/zendsvr
PHP.INI
/usr/local/zend/core/etc
/usr/local/zendsvr/etc
Web server root(s)
/www/zendcore,
/usr/local/zend/apache2
/www/zendsvr
Document root
/www/zendcore/htdocs
/www/zendsvr/htdocs
Zend Framework
/usr/local/Zend/ZendFramework
/usr/local/zendsvr/share/ZendFramework
PHP binaries folder *
* where php and php-cli reside
/usr/local/zend/core/bin
/usr/local/zendsvr/bin
PHP Log files
/usr/local/zend/core/logs
/usr/local/zendsvr/
var/log
Web user profile (assign authority to it)
NOBODY
QTMHHTTP
Default HTTP Port
:89
:10088
Admin Interface URL
http://yourIBMi:89/ZendCore/
http://yourIBMi:10088/ZendServer/
Menu (5250)
GO ZENDCORE/ZCMENU
GO ZENDSVR/ZSMENU

If the new HTTP port of 10088 seems hard to remember, you can change it to something that’s easier to work with, such as the standard HTTP port of 80. To do that, edit /www/zendsvr/conf/httpd.conf and change Listen *:10088 to Listen *:80 or whatever you want. (Of course, first ensure that no other service is running on that IP/Port combination.)

Zend Server for IBM i Is Here

Zend and IBM have announced an updated, streamlined version of their PHP package for IBM i, called Zend Server. I’ve been using the beta for a while but last week read an announcement showing it’s ready for general use. It combines the best of Zend Core and Zend Platform in one package.

To get Zend Server, go to the Zend Server for IBM i page and click the green “Free Download” button. This will give you the “Community Edition (CE)” version, the free version that handles all the basics for running PHP on IBM i. It even comes with a year of free online support.

If you want to  upgrade to the non-CE version (it doesn’t have its own name), which gives you more debugging and tracing tools, as well as Job Queue functionality and more support, you can buy a license. Write to me if you need help or want to buy a license for the non-CE version.

PHP for Batch Tasks on IBM i

Last night I gave a talk at the FASUG user group about how to use PHP as a powerful general utility language that can be called from CL programs on the IBM i. I also showed how Zend Server’s new Job Queue feature can accomplish similar goals–scheduling and automating PHP scripts–using a pure PHP interface rather than CL.

I also discussed the IBM i’s latest PHP package: Zend Server for IBM i. I explained its similarities to and differences from Zend Core.

Here are the PowerPoint slides.

Class ‘Zend_Db_Table’ not found

New developers sometimes struggle with putting all of Zend Framework’s pieces together. This week someone asked me how to resolve the error:

Fatal error: Class ‘Zend_Db_Table’ not found.

The answer: he needs to “require” the file containing the Zend_Db_Table class, like so:

or (my preference) use the autoloader:

ZF isn’t complicated if you know the few things you MUST use. The autoloader is one of them.

If you need help getting started with Zend Framework, contact me about Zend Framework mentoring, training, or troubleshooting.

Zend Server beta for PHP on IBM i: I like it

I’m recommending that people try Zend Server beta for IBM i if they’re using PHP on the IBM i. Even though it’s in beta, Zend Server brings improvements over its predecessors, Zend Core and Zend Platform. Improvements include:

  • Easy new user interface combining the best of Core and Platform
  • Better interface makes it easier for people to discover and use features such as code tracing and debugging
  • Elimination of mandatory proxy server (always a thorn in my side!)
  • Use of IBM’s supported, full-featured, flexible Apache server rather than the limited PASE server
  • Better performance

One caveat: the current beta version (as of February, 2010) is missing some functionality that will be available in the generally available (GA) release. Temporarily missing functionality includes:

  • no support for the mail() function (use Zend_Mail or Phpmailer instead in the meantime)
  • inclusion of an older version of the ibm_db2 driver. This version doesn’t have support for the “i5_libl” option. Ask Zend to send you the updated db2 driver if you need it.

I’m looking forward to trying the next beta version and eventually the GA release.

I believe Zend Server will shorten the learning curve for new users and simplify advanced configurations for us “veterans.”

PHP on IBM i (and me) at ZendCon 2009

This year’s ZendCon (Oct. 20-22, 2009, in San Jose, Calif.), the premier PHP conference, features several presentations about developing with PHP on the IBM i, including one by me!

Come hear me speak about “Zend Framework for Enterprise PHP on IBM i” on Tuesday, Oct. 20, 2009, at 4pm.

For details, go to http://www.zendcon.com.

Speaker: Zend/PHP Conference 2009

Our Zend Framework-based Site Honored by IBM/COMMON

We won! IBM has recognized my use of PHP and Zend Framework, and our entire team’s RPG/DB2 and design work, by naming our web solution the IBM i’s most innovative of 2009.

At IBM’s 2009 COMMON conference, IBM awarded the Power Systems Innovation Award for Best Web Solution for eBiz@ABG. The site, developed with my colleagues at  Strategic Business Systems, Inc., was created for New Jersey’s largest wine and spirits wholesaler, Allied Beverage Group.

The system offers product ordering, live inventory levels and pricing, and a full-text search of Allied’s large product catalog. The application was built with Zend Framework (the leading PHP framework) and runs entirely on Allied’s IBM i, leveraging Allied’s db2 database and time-tested RPG logic.

The site is password-protected, so unfortunately I can’t link to it here.

eBiz@ABG is one of the first sites to be built with Zend Framework on IBM i (System i, i5, iSeries, AS/400). It was a true collaboration with Allied, made easier because we all spoke the language of “i.” What’s more, by using large chunks of Allied’s existing RPG code that already handled the complex business logic, we saved time and avoided reinventing the wheel.

Zend Framework worked so well that I committed to mastering it and teaching the community about it. (ZF has a learning curve, but after that curve is mastered, ZF speeds development and offers easy maintenance and growth.) I earned my Zend Framework certification in August 2008, becoming one of the first 50 worldwide to do so and the first ZF-certified “i” professional. Since then, I’ve gone on to be a ZF/i mentor for other development teams, and have become a public speaker, sharing my PHP/ZF/i roadmap at conferences.

Thanks to Allied for the opportunity to collaborate on a great project; thanks to Strategic Business Systems for the support; and thanks to IBM for the award.
