A pretty cool project in PHP - Memproxy is a caching proxy "server" that uses memcached for storing the cache. This project uses PHP scripts to handle caching using memcache.

The server uses memcached to store the information and automatically manages things like TTL, custom headers and is "application agnostic" all wrapped up in a small codebase with minimal dependencies.

The PHP::Impact blog has posted a list of thirty classes and components that can make your PHP development life so much easier:

Simplicity and extensibility are the main reasons why PHP became the favourite dynamic language of the Web. In the last decade, PHP has developed from a niche language for adding dynamic functionality to small websites to a powerful tool making strong inroads into large-scale Web systems.

Their list includes software like:

• LINQ for PHP
• Doctrine
• HTML Purifier
• SimpleTest
• Phing
• PHP Security Scanner
• SimplePie
• Smarty

...and many more. Check out the full list for all sorts of useful tools.

Along with the popularity of Twitter has come one of it biggest problems - its instability. More and more people are using the service every day and some are leaving when they encounter the frustration of too much downtime. Enter a project that Graham Christensen is getting started - Stablr, a PHP-based version of the popular web service.

Stablr, the proposed name, will be the main gateway for it's users. People will post to Stablr, which will then (when it can) forward it to Twitter. If a Stablr users posts to Twitter directly, the message will be retrieved and replicated on Stablr. Responses to posts, direct messages, and tweets from friends of Stablr users would also be replicated.

He's already seen some great response from the community with offers to help and has taken it to the next level by coming up with a five-page document detailing the plans behind the project (using things like caching, an Access database and Jabber integration).

Chris Hartjes has blogged about the new CakePHP release that's on the horizon - version 1.2:

I'm certainly not the only person who has been blogging about this, but I thought I'd mention that a feature freeze is coming up for the next CakePHP 1.2 release, codenamed 'DV'. My very modest contribution this time around is a patch to fix a problem with running 'cake bake' on Windows, where it was mangling the app path that a user would enter. Ticket 4495 if anyone is interested.

He makes a few recommendations about how to get involved in the project, but also mentions some of the "trouble in paradise" that's been happening on the mailing list (not friendly for beginners?) and about the direction of the project.

Joakim passed along a note today about a new web-based frontend for XDebug:

My about page has mentioned a web based frontend for Xdebug for some time. The project has a name now: The idea for Webgrind, a spin on Valgrind, came from lack of profiling tools for PHP, particularly on OSX. Though it is possible to install kcachegrind on osx it seems overkill for many uses and is definitely not as easy as unzipping a folder to the webroot.

He and Jacob Oettinger have started up the project and have posted some initial code over on the Google Code page for Webgrind. You can check out a screenshot of it in action here too.

On his blog today, Stefan Mischook has posted his take on some of the killer PHP projects that are out there:

Part of PHP's power is actually found in the variety of open source (free to use) PHP based applications. I'm talking about things like blogs, web frameworks, forums, CMS' etc. I was just thinking, that a list of 'killer' PHP open source projects would be useful

There four on his list so far - WordPress, the Zend Framework, Drupal and Punbb.

To be totally honest about it, we've seen much of the good stuff coming out of the PHP world, in the last few years. PHP developers are leap-frogging ahead with regards to their level of skill and the quality of code they produce.

Matthew Weir O'Phinney has posted a few handy tips for PHP developers fond of working in one of the most powerful command-line editors, Vim.

I use Vim for all my editing needs -- TODO lists, email, presentation outlines, coding in any language... everything. So, I thought I'd start sharing some of my vim habits and tools with others, particularly those that pertain to using Vim with PHP.

He includes tips for things like mapping keystrokes (to the PHP interpreter and linter), using the Project plugin to make setting up projects easier and a mention (again) of ctags.

On his blog today, Johnathan Street poses a question - is PHP "good enough" to be used in the scientific community?

There is an accelerating trend in Biology to make data and tools available via web interfaces. In my opinion this is an environment where PHP excels and yet all the literature I've seen discussing the development of these services uses Perl or occasionally Java.

He came across two science-related PEAR packages that were created back in 2003, but not too much since then. He wonders if there's anyone else out there that might feel like PHP is a perfect fit for some of the sort of applications the scientific community could need.

So my question is this. Is anyone out there using PHP in a scientific environment? Are there resources available which I've missed?

David Coallier is looking for a few good men (women, children, pets who can code, etc) to join up with the PHP development group for this year's Google Summer of Code to help with the various ideas they've come up with.

Hello everyone, as mentioned a few weeks ago the most awaited Google Summer of Code is back again this year. This being said, once again the PHP Project has been accepted and we have started posting our list of ideas (http://wiki.php.net/gsoc/2008).

Some of the projects proposed include:

• PECL, website improvements and Windows Build Support
• Automatic Code Checker
• Implement Unicode into PHP 6
• Build Infrastructure and macro bindings for writing extension in D
• Rewrite the run-tests.php script
• PhD: The PHP based Docbook renderer

Be sure to check out the full list and see where you might want to get involved!

On a bit more controversial note, David Coallier has posted about a rather unpleasant experience he had at this year's PHP Quebec conference - in his own words:

As many of you know, this time of the year is usually the PHP Quebec conference and many php internals and international speakers fly to Montreal to speak. [...] This morning (2008/13/03) I saw Lukas on IRC and we said "Hey let's meet around 1pm to discuss about the PHP TestFest"

He met Lukas at the hotel, in the lounge of the hotel, not attending any of the talks. As he sits there talking to the others, a PHP Quebec staff member walks out and hands him a bill (for around 450 CAD) for attending the conference. After a little checking - both with fellow user group members and with the hotel staff as to the validity of this behavior, he could only assume that it was some "money driven" attempt on the PHP Quebec conference's side to get what they could.
