When you're building international websites, there's always something new to learn. Especially if one of the languages your website is available in uses a character set different from anything you're used to. For jimdo.com, the greatest challenge as of yet is the chinese version.

His focus isn't so much on the content of the page but on one small character that caused him headaches - the comma. Unfortunately, it seems that Unicode has its own commas that don't quite adhere to the "normal" rules to make them easy to work with (and, in his case, split with a regular expression). The fix to the situation was simple, though - adding a "u" modifier after the expression made it Unicode-aware and split the information correctly.

Just a quick heads up to let you know that that Jason Qi has published the Simplified Chinese version of my Getting Started with Zend Auth tutorial. You can find the PDF on his download site.

He also mentions an update that's been made to it (correcting a few issues) to bring its version up to 1.0.4.

There is a greater disparity with PHP use in Emerging Markets. The largest number of developers using the language can be found in Eastern Europe (39%). India and Brazil have similar usage at a little over 31%. In contrast, only 21% of Chinese developers are utilizing PHP. In North America, 35% of developers are using PHP.

They also talk about the usage rates of a few other technologies, including Flash, Ajax, Windows, and Linux.

Cal Evans also mentions these trends in this post on the Zend Developer Zone as well as linking to the full EDC report.
