Development

Translating a web application is not an easy task (although it might seem so).

2016 edit: Please note that these quick references might not be up to date anymore. Please refer to our official developers documentation at https://github.com/chamilo/docs/tree/master/1.10/en/developer for more up-to-date information. This is an update of previous development sheets of Dokeos. Now you've got them for Chamilo.

Those of you watching closely the Dokeos code will have noticed... I stopped contributing to the project in December 2009, along with my team of 12 and all of our fellow community members. The only changes we sent were actually customer requirements, so no way to avoid that. But that's it. I officially stopped working with Dokeos on January 1st, 2010. As many huge actors in the open-source (MySQL/MariaDB, OpenOffice.org/LibreOffice, ...) and PHP development world at the end of 2009, it was time for a big change.

I just realized, through Chris Shifflet's twitter feed, that there is a website called PHPAdvent, that gives a list of articles by celebrities or half-celebrities of the PHP world (including a few interesting ones about PHP advocacy). http://phpadvent.org/2008

PHP 5.3.1 is out with around 100 bugfixes + security patches. See details here

We are currently working on the development (or co-development, as a base was made available to us by the Akelos team itself) of a plugin to Akelos that fixes the current problems of language variables duplication, deprecation and need for a manual edition of the files. There are still a few things to be fixed in terms of getting that into a production environment for Akelos instead of just the develo

Just to make sure I found this again later... http://blogs.oracle.com/opal/2008/03/location_awareness_with_oracle.html gives an example of Oracle Spatial queried from PHP http://www.oracle.com/technology/tech/php/index.html is the Oracle homepage for PHP Developers

This article is clearly at level "piece of cake" for those of you working day to day with UTF-8 and unicode headaches, but I have plenty of problems with my own team to explain why they should never put a string like this:

$SomeString = "This value must not be inferior to";

in the Dokeos translations system, but they never learn :-) This would later appear in the code as something close to:

echo get_lang('SomeString');

and this would make it available in all the supported languages (if translated by a good will in his own language). So here i

I have updated my system early to Ubuntu 9.10 (Karmic Koala) and, to my surprise, there is a little change that could cause dramatic problems in Zlib (library dealing with compressed data). The gzopen() function has been changed to gzopen64(). This means that all calls to gzopen() in the PHP bindings for that library should probably be modified to use gzopen64(). In Dokeos, we use PclZip 2.6, which doesn't use gzopen(), apart from a check to see if the zlib extension is installed or not.
