PHP 5.3 has been out of maintenance for about three months now and it seems like it's time for the community to move on at last. Drupal8 will target 5.4. Symfony announced the results of a poll about which PHP version Symfony3 should target (TL;DR: 5.5 and 5.6 are preferred). And Pascal Martin released yesterday an update on his PHP usage stats based on scanning server headers.
Pascal's number are interesting but I believe they have a bias towards older PHP versions. I would argue that people configuring their servers properly are also those that tend to keep up to date with newer versions, and part of the best practices is to avoid publishing the software versions you are using (i.e. disable expose_php in php.ini). If I am correct here that means early adopters are mis-represented in those numbers.
In any case, I do have another biased dataset to present so here it comes! I looked in the packagist.org logs of the last fifty days for
GET /packages.json which represents a composer update done by someone. Since Composer sends the PHP version it is running with in its
User-Agent header, I can use that to see which PHP versions people are using Composer with. Of course this data set is probably biased towards development machine and CI servers and as such it should also be taken with a grain of salt.
PHP usage statistics
I have two datasets, from November 2013 and today, which shows the progression of various versions. Any version below 3% usage has been removed to keep things readable.
|PHP 5.3.10||490350||11.92%||PHP 5.4||2069021||50.31%|
|PHP 5.3.3||419871||10.21%||PHP 5.3||1533073||37.28%|
|PHP 5.4.20||387450||9.42%||PHP 5.5||510596||12.41%|
|PHP 5.5.9||2475970||21.42%||PHP 5.5||5647892||48.87%|
|PHP 5.4.4||1022498||8.85%||PHP 5.4||3305929||28.61%|
|PHP 5.5.17||678997||5.88%||PHP 5.3||1716653||14.85%|
|PHP 5.5.16||529227||4.58%||PHP 5.6||886260||7.67%|
A few observations: 5.3 really is on the way out, 5.5 is now the major platform, 5.6 adoption is lagging behind last year's 5.5 adoption a little bit which is unfortunate but can perhaps be explained by the fact Ubuntu 14.04 ships with 5.5.9
PHP requirements in Packages
A second dataset I looked at is which versions are required by all the PHP packages present on packagist. I split it in two groups: those that required a given version at any point and those that require it in their current master version.
PHP Requirements - Anytime - November 2014
PHP Requirements - Current Master - November 2014
A few observations: almost 7% of packages that required 5.3 and 15% of those requiring 5.2 gave these up for higher requirements, that's pretty low but it's a start. 5.4 is getting a good foothold but 5.5/5.6 features are hardly used by OSS packages.
Again these numbers need to be taken with a grain of salt, but looking at the ecosystem from this perspective I would say PHP 5.3 can be safely dropped by most libraries and 5.5 sounds like a promising target!
TL;DR: New shiny product to support Composer development: Toran Proxy
A bit of history
I have spent quite a large part of the last three years working on both Composer and Packagist. This has been great fun for the most part, I learned tons, met a gazillion people both online and offline, got to travel places to talk about it at conferences. One question I get asked frequently is how I find the time to work on this for free, and my answer until recently was along the lines of: "I run my own business, which affords me quite some flexibility".
The problem is that I can not use this answer anymore. We have changed Nelmio's business model a few months ago to focus more on consulting and contracting. While this does not change the amount of time I can decide to spend on open source, it means that if I keep working the way I did in the past I will have to move under a bridge sooner or later.
Open-Source or a Salary?
I have spent quite some time over the last few months evaluating options to get out of the current situation. Having to choose between working on open source or earning a living is not great, and I feel horrible for ignoring GitHub issues and such. So the one thing I settled on is to work on an product around Composer that helps businesses using it but does not take anything away from the regular users.
Introducing Toran Proxy
Toran Proxy does mainly two things at the moment: it proxies Packagist, GitHub and others to make Composer faster and more reliable, and it allows you to host private packages easily. This was already sort of possible with Satis and many people used various amounts of hackery to get there. Toran makes it easier and faster. It integrates better with Composer since it acts as a real proxy. It can fetch/build packages lazily or can build them ahead of time, enabling you to choose between a lower disk usage or more safety against GitHub outages and such.
It comes with a yearly license fee, which includes updates and will hopefully allow me to work full time on improving Composer & Packagist. There is quite a big backlog of issues to look at and pull requests to review, finalize and merge. Packagist also has tons of potential for improvement. I have a million ideas and I really hope I get the chance to work on them. For example improvements in the discoverability of packages alone would benefit most everyone in the PHP community.
Of course Composer and Packagist remain free to use and fully open source. There is no way that will change. I just hope I can continue to work on them, for the community and supported by the community. Check it out!
Up until today if you run a home-grown package repository serving private packages it was quite a pain to use with Composer. You did not have efficient way to password-protect the repository except by inlining the password in the composer.json or by typing the username/password every single time.
With the merge of PR#1862 and some further improvements you can now remove credentials from your composer.json! The first time Composer needs to authenticate against some domain it will prompt you for a username/password and then you will be asked whether you want to store it. The storage can be done either globally in the
COMPOSER_HOME/auth.json file (COMPOSER_HOME defaults to
%APPDATA%/Composer on Windows) or also in the project directory directly sitting besides your composer.json.
You can also configure these by hand using the config command if you need to configure a production machine to be able to run non-interactive installs. For example to enter credentials for example.org one could type:
composer config http-basic.example.org username password
That will store it in the current directory's auth.json, but if you want it available globally you can use the
The advantage of having it in a separate file is that you can easily add this auth.json to .gitignore and let every developer in your company have their own credentials in there.
And I did not forget the security-minded folks that do not want to store anything on disk and do not want to be prompted every time! You can use
composer config -g store-auths false
Altogether these small improvements should make some use cases much easier so that is great news.
Here is a short update on the conferences I will attend in the coming months, in case you want to meet or if you are just looking for a good one to attend:
Next month I am very happy to have the chance to visit Tunisia for the first time and go speak about Composer at the Symfony Tunisia event. It will also be the first time I give a talk in French, which freaks me out a bit since I am so used to speaking about technical matters in English. You can therefore expect a bastardized language known as Frenglish.
Right after that is the first SymfonyCon happening in Europe, which will be in Warsaw, Poland. And I hear it is almost sold out so in case you were thinking of going hurry up and grab a ticket now.
In January I will head back to my mother nation of Belgium (insert "while it is still a country" joke) for two events: first I will speak at PHPBenelux about web application monitoring with Heka. Then the weekend after there is FOSDEM where I hope I can also meet a few people from outside the PHP community.
Why? To keep it short, Liip is a great company to be employed at - and they're hiring - but both Pierre and I have had the urge to be our own bosses for a while, and that is something that's hard to suppress. Eventually we had to give in.
Slippy is a HTML Presentation library written with jQuery, it takes a html file in and plays it in any browser.
It is optimal for programming-related talks since it includes a syntax highlighter and is very easy to use since it's just standard html markup with a few classes to enable specific functions.
Obviously feedback is very much welcome and even though it's not perfect yet, I hope it'll be useful to others. More docs and styling fixes (the dark grey background wasn't too visible on a projector, my bad) should come soon as I have more talks planned, and the slide repository page will receive some love as well when I have time.
I would like to attract everyone's attention on the 0.3-alpha release of Arbit.
For those that do not know Arbit yet, it is a project management and issue tracker build in PHP. It uses CouchDB as a storage backend by default but work to support RDBMS via PDO is in progress.
Interestingly, it also provides experimental support for continuous integration, also fully PHP-based, unlike other popular solutions. This is not enabled by default in this release since it isn't fully ready but feel free to stop by the irc channel (#arbit on freenode) to know more.
The full announcement contains details about what we fixed and implemented in the 0.3.
As all open source projects, Arbit needs your help, I joined the project early this year and we have had a few contributions from other people since then, but we can always use more help. Therefore if you are interested and wish to take part by developing new features, fixing bugs or at least reporting them, please don't hesitate and get in touch! And as Elizabeth Naramore's article recently pointed out most people are afraid to contribute, I would like to say that no matter how skilled you are, contributions are welcomed. We will provide assistance if needed.
In recent news, this site got a new design, I thought I could make the content more readable and accessible, so I killed my old templates and style sheets and started from scratch, without photoshop this time.
There is also mobile browser (android/iphone) support which is by the way achieved with this very interesting CSS media instruction:
<link rel="stylesheet" type="text/css" href="/mobile.css" media="only screen and (max-device-width: 800px)" />
This means any device with a monitor less than or exactly 800px wide will load the mobile.css file on top of the default one. Note that using media="handheld" is not working for recent smartphones that consider themselves greater than old school internet-enabled cellphones, so this is the only way to do it.
Any feedback, especially bad, is appreciated.
As part of my work on my CMS (and website as this site is running on it), I decided to code a RSS feed builder. This could easily be made as a standalone class so I thought I would share it.
The package is made of two files, one being the feed and the other one representing an item (i.e. an article). It works nicely as you can see from all the feeds I set up in here, and it supports the RSS2.0 standard entirely.
