International PHP conference in Frankfurt 2007
Yesterday was the first day of the International PHP Conference. I listened to Lars Jankowfsky in his session “Practising Agile Development”. Although different methodologies were mentioned it was mainly a one day session on how Extreme programming works. The session had a good mix of fun och seriousness. One of the reasons I wanted to [...]
Reordering nested sets using PHP and Javascript
The adjancency method
Representing a tree of nodes, for example product categories, in a relational database is not hard. The most common way of doing it is to store a parentid with each node. This is also known as the adjacency list model. It is sometimes also referred to as the recursive model. Whatever the name [...]
PHP Conference
I have been to the International PHP Conference in Frankfurt a couple of times. Last year I didn’t go as the quality of the conference 2005 wasn’t what I think one should expect.
This year seems to be different though. A whole slew of interesting sessions on PHP mixed with a few sessions on agile development. [...]
Generating Excel files with PHP
I’m on this project at work where we need to create an excel file and send it via email or ftp to a recipient. The normal answer to this is to create a comma separated file and name it .xls and excel will work it out. However, that only works if you open it directly [...]
SVN hosting options
At work we still use CVS. We even have PVCS sitting on an old Tru64 machine actively used in one last project that hasn’t converted to CVS. I have looked at subversion/SVN and I use it for a few smaller projects. I host the repositories myself which is not the right option in every situation. [...]
PostNuke and PHP 5
In an earlier blog post I wrote about how I think companies, and open source projects, will loose business if they don’t start the upgrade path to PHP 5. With PHP 6 in the works it is only a matter of time before most people will consider PHP 4 applications legacy. Now that there is [...]
Problem sending mail with PHP mail function
Occasionally I have had trouble sending emails using the builtin mail() function in PHP. Sometimes emails never reached their intended destination. Naturally I have assumed that there might be a problem with some spam filters used. However, lazy as I am, I have not given it a second thought. Instead I have used a PHP [...]
The nested set model – hierarchical data in MySQL
I’m working on a small PHP project handling data which is organized in a hierarchical fashion. This is a common task and I have done it before creating forums and the like. This time no different than any other I was swearing over the rather ugly and most of all inefficient code needed for fetching [...]
Zend Feed for a Swedish web development blog aggregator
Lately I have begun to get more and more annoyed with my feed reader. I use a simple feed reader which lack most features except for subscribing to and reading feeds. The one thing that annoys me the most is that it can’t aggregate several feeds into one feed. Yesterday I finally decided to scratch [...]
Losing market share with PHP 4
It looks like PHP 4 is still going strong as a worried Clay Loveless write on his blog. Ivo Jansch have an older article, PHP 5 adoption – a summary, on the subject. It is true that the PHP 5 uptake has been slow. Many internet service providers as well as many developers are reluctant [...]
