From time to time I write some code snippets, which I find really hard to debug, and the code does not do, what it is expected to do. Especially when the code is not tested directly, but only executed in some a bit more complex environment. Those are 4 typical errors I introduced in my code, and spend some time debugging it, because I found them really hard to spot. Luckily, once I spotted the actual bug, I find it a lot easier the next time the typo occurs. Therefore I want to share those, so that I may save you some minutes of your life hunting stupid bugs. read more…
After a quite long time, a lot of bug fixes and major changes, with several new features, modules and themes, I finally managed to release the successor of kPortal: Torii. read more…
Manuel just released a new version of phpUnderControl, which is now hosted on phpunit.de and got a new layout. Read on for details... read more…
By order of dynamic webpages and phpzertifizierung.eu (both german) I gave three trainings, which I just finished. The topics included: "Regular expressions", "Testdriven development with PHPUnit" and "Image creation". The slides are online now. read more…
One of the members of the PHP Usergroup Dortmund, Manuel Pichler, just made a first release of phpUnderControl. This is a distribution and patchset for CruiseControl to offer you access from the webinterface to statistics you can get out of PEAR::Code_Sniffer and PHPUnit with its recently added new metrics. Read on for details... read more…
In the meantime tagging, as a folksonomy, is often nearly used as equivalent to the whole Web-2.0-hype. Nowadays you can't develop any new application without adding tags, and I wanted to do the same. But reviewing the system in a bit more complex environment shows some major flaws, which can also be detected in the implementations of simple applications. This article lists some structural problems, and will be followed by other articles describing solutions for some of these cases. read more…
With recursive patterns in PCRE you can actually match recursive structures, even you should not try this. A regular expression to validate BBCode documents is included in the blog post. read more…
I just finished my both talks at the IPC 07, a quick talk on MockObjects and a talk abaout regular expressions including a description of the new features, like condidtional subpatterns and recursive matches. read more…
Tobys and my book about eZ Components, published by Galileo Computing, has passed the second gelley-proof and will be published very soon. read more…
The discussion on my blog post "Do not use regular expressions for parsing" ended in a discussion about BBcodes in general. I just used them as an example to demonstrate why it it is impossible to parse such a language with regular expressions - and mentioned in a subclause, that I don't see any sense in using them at all. So why use them at all? read more…
