On his blog, Stuart Herbert has a quick tip showing how to mimic a feature of Ruby on Rails:   I'm still working on the next article in my series looking at PHP on servers, so in the mean time, check out this simple way to emulate Ruby's nice way of handling separate getter, setter and state query methods in PHP.   He admits his example isn't as elegant as the Ruby method, but it does get the job done. Code for the method is included in his post ready for cut and pasting.

Andrei Zmievski has posted something new to his blog today about a feature of PHP6 that's finally been hammered down - HTTP input (request) decoding.   There have been no fewer than 4 different proposals floated before, but this one combines flexibility, performance, intuitiveness, and minimal architectural changes, and has only a couple of small drawbacks. Let's take a closer look.   He details the functionality - what it is, what's been decided on, and the advantages of the method. The basic approach is a "lazy" one where PHP will only store the request when it comes in, no filtering or anything, until you want to do something with it (i.e. get it via $_GET, $_POST, etc). When the request for data is made, PHP looks at the encoding settings and formats the data accordingly.   Advantages he mentions for this method include removing the guess-work on PHP's part for which encoding the request is and that it removes some of the overhead by not processing the data until it's actually needed.

D-Wave talks big, investors impressed D-Wave Systems has attracted a lot of criticism from computer scientists over claims it has developed a way to create a marketable quantum computer. But whether its technology will ever be viable outside of a laboratory setting or not, investors seem to be eating it up.â¦
