Greg Beaver, noting some issues that Derick Rethans had pointed out about namespace support for upcoming PHP versions, has posted about a patch he submitted to solve the problem simply.

The issue Derick pointed out:

In PHP 5.3 this would alias the class Interval in the namespace PEAR::Date to the class Interval. For now, this code would work just fine. However, if PHP would introduce a class "Interval" at some point in the future (and PHP can do this as it owns the global namespace) then the above code would suddenly stop working.

Greg's patch makes it possible to "override" the internal class if need be, making it so that code currently working wouldn't break. All it takes is to "use" is like you normally would and and the magic happens behind the scenes.

In this post on the Dokeos blog, there's a comparison of the mbstring function and the iconv library as it pertains to their use on multi-byte strings.

I was wondering today why use mbstring rather than iconv in Dokeos, and honestly I didn't remember exactly why I had chosen mbstring in the past, but finding information about the *differences* between the two. [...] Searching a bit more, I found a PPT presentation from Carlos Hoyos on Google.

Essentially, it boils down to how the library is integrated - mbstring is bundled and iconv is pulled from an external source. So, if you're looking for maximum portability, he recommends mbstring.

On the Stubbles blog, Frank Kleine offers some advice to developers looking to use the Reflection API - "don't trust it".

If you try to get informations about parameters from methods of internal classes - forget that. Examining several internal classes my key findings are: either there is no information about parameters available and the reflection API says the method does not have any parameters, or the information about the parameter is wrong.

He includes code examples along side the output from the script to illustrate his point.
