PHP date.timezone warning fix

OK, Have you gotten this (or similar): PHP Warning: PHP Startup: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for '-8.0/no DST' instead in Unknown on line 0 I am running PHP 5.3.0 on my Windows XP, and have spent the better part of the day to try to get rid of this warning and finally managed to do it. How, you say? The breakthrough came after I have read this instructions from the PHP web site Changes in PHP datetime support . Here is part of it: Since PHP 5.1.0, there has been an extension named date in the PHP core. This is the new implementation of PHP’s datetime support. Although it will attempt to guess your system’s timezone setting, you should set the timezone manually. You can do thi

"B.S." Stands for Business-Speak

Today I have read this very interesting article on the American Management Association web site about the need of communicating clearly and avoid empty words. You can read the business speak article here.

Flare Data Visualization

Flare is an ActionScript library for creating visualizations that run in the Adobe Flash Player. From basic charts and graphs to complex interactive graphics, the toolkit supports data management, visual encoding, animation, and interaction techniques. Even better, flare features a modular design that lets developers create customized visualization techniques without having to reinvent the wheel. View the demos and sample applications to see a few of the visualizations that flare makes it easy to build.

Zend, Microsoft, IBM join forces to simplify cloud-app devlopment forPHP coders | All about Microsoft |

As this article says all the right buzzwords are part of a newly unveiled Simple API for Cloud Application Services . It’s an open-source initiative that currently includes Zend, Microsoft, IBM, Nirvanix, Rackspace and GoGrid as the founding members. (No Google and no Amazon, however.)

A Role-Based Access Control (RBAC) system for PHP

Anyone, that has searched the web for anything related to PHP, sooner or later must have come across the web site of Tony Marston . It is very rich source of ideas and information, and it is worth visiting any time you have a moment to spear. One of the topics that web developers tackle often is the issue of providing accurate and flexible access to the web site users. One way to do this is by using RBAC or Role-Based Access Control system. This system is most ofter implemented with a database, but this is not a requirement. Recently I looked again at one of Tony Marston’s articles about RBAC implementation for PHP and I thought, I share the link with you. I hope it will help or inspire somebody. Enjoy!

Modular applications in ZF 1.8

OK, so you jumped ahead and upgraded to Zend Framework 1.8. What now? One of the new features, that came along with this new release, was the possibility of individual module bootstaping. Or.. does it? If you find the whole thing about module bootstraping confusing, read this blog post and may be it will become a little bit clearer. It was for me. Let us know how you did. Happy coding!

Have you made the jump to Zend Framework 1.8?

Over the weekend I have finally made the jump to 1.8. There, of course, are few changes in this new version, some of the most significant is the introduction of Zend_Application and Zend_Tool. Several blog posts helped me along the way, but I should be honest with you, it took me a good number of hours to assimilate the new “Bootstrap.php” paradigm and move my project to the the new way of doing bootstrapping. If you are starting new project, take a look at this clean writeup . I, however, was not starting a new project and needed something that will accommodate a modular directory structure. A good start was this blog post . I hope this two links will help somebody to make the jump to the new Zend Framework version less painful.


One of the best Phing resources I have come across is the blog of Raphael Stolt . I have used Phing based scripts for backup and code generation, but that is not all you can do with it. As Raphael is showing in its blog, you can use it for unit testing, phplocing (see my post on phploc), refactoring, code sniffing, database generation and so on.


phploc is cool tool, by Sebastian Bergmann , to check the size of your php project. You can install it with PEAR. The short version of the installation goes like this: // add PEAR channel user@host ~ % pear channel-discover // install phploc user@host ~ % pear install phpunit/phploc // run user@host ~ % phploc /path/to/your/project/code/folder For more detailed instructions and system requirements, here is the link.
