Nikita Popov's Blog: Understanding PHP's internal array implementation (Part 4)

Thu, 29 Mar 2012 09:16:02 -0500

Nikita Popov has posted the fourth part of the "PHP's Source Code for PHP Developers" series he and Anthony Ferrara have been posting. In this latest article in the series, Nikita looks specifically at PHP's array implementation and how it's handed "behind the scenes".

Welcome back to the fourth part of the "PHP's Source Code for PHP Developers" series, in which we'll cover how PHP arrays are internally represented and used throughout the code base.

He starts with an obvious foundation: "everything's a hash table" (even properties, classes and yes, arrays). He describes what a hash table is and talks about two of the most commonly used versions of it in the PHP source - HashTable and Bucket. He gets into their usage a bit and compares this to the corresponding PHP code that uses a standard array.

Nikita Popov's Blog: Understanding PHP's internal function definitions (Part 2)

Mon, 19 Mar 2012 08:17:48 -0500

Following this recent post from Anthony Ferraara about the source code of the PHP language itself, Nikita Popov is working with him and has produced the second part of the series, a look at finding the internal function definitions for the PHP functions you use every day.

In the previous part ircmaxell explained where you can find the PHP source code and how it is basically structured and also gave a small introduction to C (as that's the language PHP is written in). If you missed that post, you probably should read it before starting with this one. What we'll cover in this article is locating the definitions of internal functions in the PHP codebase, as well as understanding them.

He starts with a basic example - a string function, strpos. He shows a handy searching trick to help find the actual function definition and which matches should be given priority. He lays out a typical skeleton of a PHP function definition and gets into some detail as to what this particular function does (in C). He briefly mentions the Zend Engine functions and a look ahead to finding classes and methods.

DZone.com: DevOps for Devs in 3 Steps (Presentation)

Wed, 19 Oct 2011 10:57:25 -0500

In the "DevOps" section of DZone.com today Mitchell Pronschinske has posted the slides for a presentation he gave at the WebTech 2011 conference titled "DevOps for Developers". It gives a good perspective for those used to the coding side of things on what's out there for the server an beyond.

A presentation entitled "DevOps for Developers" was given at the WebTech 2011 conference and now the slides are up online for all to see. I'll summarize the show and let you know where the better slides are so you don't have to flip through the whole thing. It starts out on an introductory level, but then it gets into some tools and techniques that are talked about less often.

Technologies mentioned in the presentation include more familiar development tools like PHP, Apache, HipApache, Gearman, NoSQL and Memcached. There's also some examples of more "devops" things like Vagrant, Puppet and WetWare.

Cal Evans' Blog: How do I find good PHP developers?

Tue, 14 Sep 2010 12:22:14 -0500

If you or your company is looking to hire on PHP developers but are having trouble finding good, qualified people, you should check out some of the advice that Cal Evans has posted to his blog to help you out.

Twice this week I got asked a similar question, "How do I find good PHP developers to hire?" The first one was a recruiter who had originally tried to hire me because she "read my resume". [...] The second one, however, was a just someone trying to find PHP developers for his team. Since he wrote me a nice email asking advice, I decided to reply in kind. Three pages and one thousand words later, he had my answer.

His answer included seven different points companies/recruiters could possibly follow to help them get the right people on board:

posting jobs on phpdeveloper.org (yes, shameless self-promotion)
PHP User Groups
Getting involved in the community
Considering telecommuters
Attending conferences
Getting your developers to write about your company/work environment
Do things that make your developers want to sing your praises

Chris Hartjes' Blog: Twitter Asks: Continuous Integration Landscape for PHP Developers

Wed, 08 Sep 2010 10:42:42 -0500

After asking for topics to blog about on Twitter, Chris Hartjes has posted the first response to the suggestions - a look at continuous integration (CI) in PHP environments.

For those not familiar with the concept of Continuous Integration, I can sum it up with one very glib phrase: it lets you break your code before you buy it. [...] If I were to design a Continuous Integration (hereafter referred to as CI) system, what would it look like?

His requirements include version control integration, easy unit test execution, a web interface and be able to automate it all at a moment's notice. He talks about the importance of unit testing in CI and the tools that are available for the job like phpUnderControl, Xinc and Hudson. He also looks at the build process, from check-in through a successful build result and how he handles bugs when they do pop up.

WebHostingHero Blog: A Look at the Original PHP Developers

Wed, 28 Jul 2010 09:44:23 -0500

On the WebHostingHero blog today there's a new post going back to the roots of the PHP language and some of the original contributors like Rasmus Lerdorf, Zeev Suraski and Andi Gutmans.

When PHP began in 1995, it represented a fork on common object oriented programming languages. Designed to help provide scripting for the web, the language took on a life of its own as it became one of the primary web development standards. Today, PHP is used by millions worldwide and powers a majority of sites.

They talk about how some of the original developers are active in helping to better the languages (directly and indirectly) and how the advocacy of the community has helped it grow even stronger over the years. There's also mini-spotlights on each of the three mentioned above.

Community News: Adobe Seeks PHP Developers for Pre-Release Access on Flex Builder

Mon, 06 Apr 2009 12:53:07 -0500

Andi Gutmans mentions a program Adobe is starting up concerning Flex and PHP and they're looking for some developers to get in on it.

In this upcoming version [of Flex Builder], a significant new set of features are being introduced to accelerate creation of data-centric applications with PHP on the server-side leveraging Zend Framework and Zend AMF. Prior to the public Beta later in the year, Adobe would like to invite a select group of PHP developers into a private pre-release program for Flex Builder.

The group would get a sneak peek at the upcoming features, work with the development team and help to make the product into something the community really can use. If you'd like to get in on the program, fill out this survey and they'll get in touch with you with more information.

Zend Developer Zone: Adobe Survey for PHP Develoeprs

Wed, 14 Mar 2007 12:02:00 -0500

The Zend Developer Zone has posted about a new survey that Adobe is doing to try to get to know some of the web developers out there.

Adobe is hoping to play a little SHOW and TELL with PHP developers. We SHOW you what we are working on, you TELL us if you think we've got it right. Please take a minute to complete the survey we have posted here: http://www.surveymonkey.com/s.asp?u=540413426135

If they think you're a good match, they'll get in contact with you. There's also a gratuity of $150 to compensate for your time for the talk.

SitePoint Ruby on Rails Blog: PHP developers most likely to switch to Rails

Mon, 09 Oct 2006 08:06:49 -0500

Matthew Magain has some interesting observations over on the SitePoint Ruby on Rails blog today - specifically that PHP developers are the most likely (out of those working with other web-based languages out there) to make the switch to Ruby on Rails.

Of all the graphs in The State of Web Development 2006/2007 report that SitePoint and Ektron published recently, the one that stood out the most to me was the one showing the platform currently being used by developers planning to start using Ruby on Rails.

It wasn't the fact that the graph shows PHP developers to be likely to start using Rails-this makes sense, as someone is more likely to experiment with another open source platform if they're already using another open source platform-it was the fact that PHP developers are more than three times as likely to start using Rails, even more so than Java developers!

Unfortunately, the study mentioned isn't too cheap, otherwise it would be interesting to see the info behind this graph....
