SitePoint PHP3 Ways to Implement Embeddable Custom Badges (20.12.2014, 17:00 UTC)

One great way of organically promoting your application is to provide “badges”; snippets of content that people can embed on their own websites.

This can contain up-to-the-minute information from your application about a user, piece of content or another object, dynamically generated and inserted into other websites. This is probably best illustrated with some examples:

Some examples of embedded content

In this article I’m going to take a look at some of the ways you can implement this.

Setting up our Example Application

All the code from this tutorial is available on Github. There’s also an online demo.

First, we’ll define our application’s dependencies using Composer:

"silex/silex": "~2.0@dev",
"twig/twig": ">=1.8,<2.0-dev",
"smottt/wideimage": "dev-master"

Anthony FerraraOn PHP Version Requirements (19.12.2014, 19:00 UTC)
I learned something rather disturbing yesterday. CodeIgniter 3.0 will support PHP 5.2. To put that in context, there hasn't been a supported or secure version of PHP 5.2 since January, 2011. That's nearly 4 years. To me, that's beyond irresponsible... It's negligent... So I tweeted about it (not mentioning the project to give them the chance to realize what the problem was):

<script async src="//platform.twitter.com/widgets.js" charset="utf-8">
I received a bunch of replies. Many people thought I was talking about WordPress. I wasn't, but the same thing does apply to the project. Most people agreed with me, saying that not targeting 5.4 or higher is bad. But some disagreed. Some disagreed strongly. So, I want to talk about that.

SitePoint PHPNo More var_dump – Introducing Symfony VarDumper! (19.12.2014, 17:00 UTC)

Recently, Symfony went from Zend-like bloat and rigidity to extreme decoupling and modularity. With the new Developer Experience initiative, Symfony has done a Laravel-style 180° and dove right into making its components more end-user friendly, its docs more complete, and its AppBundles unbundled, simplifying entry and further development almost exponentially. Considering user friendliness, it’s a long way from “best pals friendly” but it’s definitely no longer hostile. One factor that contributes to this factor a lot is their continuous pushing out of new components that are incredibly useful outside of Symfony’s context. One such component is the new VarDumper.

SYMFONY LOGO

Why?

You’re developing a feature. You either don’t feel like writing tests, or what you’re developing needs some variable testing in the middle of a function - something you can’t quite cover with a test. Inevitably, you resort to something like die(var_dump($var));. Even if you’ve abstracted it into a shorthand method like vddd($var), it’s still clumsy and unreadable, and tends to leave debugging snippets around your code, either as comments or, even worse, as code that can actually be triggered.

There’s little choice in the matter - sometimes we simply need our vddds. And sure, if you’re an Xdebug user, you’re probably used to a slightly better looking output than the raw PHP prints. Still, few good solutions existed that beautified this output for us enough to make it worth installing a dev dependency. Until VarDumper.

Evert PotTesting your composer dependencies with prefer-lowest (18.12.2014, 22:54 UTC)

A few days ago, a new feature landed in composer, the --prefer-lowest argument.

Normally, for any dependency, composer will attempt to always install the latest possible version.

For instance, if your composer.json looks like this:

"require" : {
    "vendor/package" : "~1.2.1"
}

Then you are telling composer effectively that it should install any version after 1.2.1, but before 1.3.

If version 1.2.5 is the latest, composer will always grab that version.

With the new --prefer-lowest setting, you can tell composer to install the oldest possible version of a package that still matches your requirement.

So if we run:

composer update --prefer-lowest

We should get version 1.2.1 for vendor/package and all its dependencies.

Why is this useful?

In some projects, there may be packages lying around that are not the latest version. This could be because it introduced some BC break, or introduced a bug.

If other packages also use the package that's being held back, they may get an older version as a dependency.

So for package maintainers, they will want to find out if their package correctly works with the oldest package they claim to support.

So for us to test this, we can simply run:

composer update --prefer-lowest
./bin/phpunit

If our unittests break with older dependencies, we know that we either need to increase the oldest supported version, or implement a workaround so it still works.

Automating this with Travis

If you are using Travis for automated testing, you can also tell travis to test with the oldest possible dependencies.

Travis allows you to add new lines to the build matrix with the env: setting, which makes this super easy to do.

If for instance your .travis.yml looks a bit like this:

language: php

php:
  - 5.4
  - 5.5
  - 5.6
  - hhmv

before_script:
  - composer update --prefer-source

script:
  - ./bin/phpunit

You can modify it to this, to allow Travis to do 1 build for the latest, and one build for the oldest possible depdendencies:

language: php

php:
  - 5.4
  - 5.5
  - 5.6
  - hhmv

env:
  matrix:
    - PREFER_LOWEST="--prefer-lowest"
    - PREFER_LOWEST=""

before_script:
  - composer update --prefer-source $PREFER_LOWEST 

script:
  - ./bin/phpunit

This would result in a total of 8 builds.

Anthony FerraraStack Machines: Compilers (18.12.2014, 20:31 UTC)
I have the honor today of writing a guest blog post on Igor Wiedler's Blog about Compilers. If you don't know @igorwhiletrue, he's pretty much the craziest developer that I know. And crazy in that genious sort of way. He's been doing a series of blog posts about Stack Machines and building complex runtimes from simple components. Well, today I authored a guest post on compiling code to run on said runtime. The compiler only took about 100 lines of code!!!

SitePoint PHPEfficient Chinese Search with Elasticsearch (18.12.2014, 17:00 UTC)

If you have played with Elasticsearch, you already know that analyzing and tokenization are the most important steps while indexing content, and without them your pertinency is going to be bad, your users unhappy and your results poorly sorted.

Even with English content you can lose pertinence with a bad stemming, miss some documents when not performing proper elision and so on. And that’s worse if you are indexing another language; the default analyzers are not all-purpose.

When dealing with Chinese documents, everything is even more complex, even by considering only Mandarin which is the official language in China and the most spoken worldwide. Let’s dig into Chinese content tokenization and expose the best ways of doing it with Elasticsearch.

Chinese characters are logograms, they represents a word or a morpheme (the smallest meaningful unit of language). Put together, their meaning can change and represent a whole new word. Another difficulty is that there is no space between words or sentences, making it very hard for a computer to know where a word starts or ends.

There are tens of thousands of Chinese characters, even if in practice, written Chinese requires a knowledge of between three and four thousand. Let’s see an example: the word “volcano” (火山) is in fact the combination of:

  • 火: fire
  • 山: mountainsky

Our tokenizer must be clever enough to avoid separating those two logograms, because the meaning is changed when they are not together.
