Kinsta Blog:
HHVM vs PHP 7 - The Competition Gets Closer!
May 26, 2015 @ 10:19:02

In this new post to thier blog Kinsta shares benchmark results comparing PHP 7 to HHVM, both in their own experience and some shared from other companies too.

A few years ago, engineers at Facebook went on a swashbuckling mission to rebuild the foundation of the world's most populated social network struggling to sustain acceptable performance levels. PHP was all the rage a decade ago when Facebook was gaining steam and pursuing a global target audience.

As they put it the "competition is getting closer" and the performance gap between the two is growing smaller and smaller. They talk some about the performance improvements and new features that are being worked into PHP 7 and some speculations around a Just-In-Time engine and asynchronous programming features. Then comes the benchmarks. They provide the specifications of the machine they tested on and the results of tests runs of WordPress and Drupal (based on requests per second). The rest of the article talks about two stories from other companies using HHVM, Etsy and WikiMedia, and some of the lessons that have been learned along the way.

Damien Seguy:
Prepare for PHP 7 error messages (Series)
May 26, 2015 @ 09:35:11

For those looking forward to PHP 7, there's a new series of posts from Damien Seguy that can help you with some of the newer error messages and what might be causing them.

The first step to prepare for PHP 7 is to lint it : using the command line instruction 'php -l script.php', one can easily check that every file in a current application compile with PHP 7. The second step is to run the application and the unit tests : in short, execute it with PHP 7. And this is where we'll learn about the new errors that PHP has prepared for us. In order to be one step ahead of the migration, this article will help you prepare here is a panorama on PHP error messages.

In part one he looks at some of the most often raised errors including the incorrect use of "$this" and undefined offsets. Part two gets into a few more complex messages about return type hinting, the constant scalar expression and using temporary expressions in a write context. Finally, part three looks at messaging around redefinition of identical parameters, bit shifting by a negative number, named constructor deprecation and strict typing. Each part of the series covers a few more than just the ones listed here too, so be sure to check each for more helpful error messages and solutions.

Marc Aube:
Design Pattern Specification
May 25, 2015 @ 12:19:47

Marc Aube has a new post to his site that introduces you to the specification design pattern, a technique that's useful for ensuing the current state of an object is valid.

The specification pattern is a software design pattern used to codify business rules that state something about an object. These simple predicates determine if an object's state satisfies a certain business criteria. They can then be combined to form composite specifications using logical operators. Use a specification to encapsulate a business rule which does not belong inside entities or value objects, but is applied to them.

He suggests a few things the pattern could be useful for like validating the current state or define how an object should be created. He gives a few more "real world" examples and then gets into the code to create a custom specification. In his "CustomerIsPremium" spec he defines a single method on an interface to determine if the Customer given is correct. He then creates a class instance and encapsulates the logic inside its "isSatisfiedBy" method. He also includes a bit more complex example, showing how to create a composite specification for handling grouping like "and", "or" and "not" assertions. Finally he looks at how to build specifications that can be passed in and used as selection criteria. He does point out that this can leak database handling into the specification layer, however, and should really be avoided without a inversion of control method in place.

Mikkel Høgh:
Drupal is still a gated community
May 25, 2015 @ 10:16:42

In a recent post to his site Mikkel Høgh makes the suggestion that Drupal is still a gated community, mostly as it relates to the process around the "Project Applications" process.

One of the things the Drupal community prides itself on, is how open the community is. And that is generally true, but there's one exception. And that is the Kafkaesque horror-show we subject any newcomers that would like to publish their code on Drupal.org to. It goes by the name of "Project Applications". I know several people who've hit this wall when trying to contribute code. It's not uncommon to wait several months to get someone to review your code. And when it does happen, people are often rejected for tiny code style issues, like not ending their comments with a period or similar.

He talks about other factors involving reviews and delays that can also cause authors to abandon their work and feel "unwelcome and unappreciated". He mentions the "review bonus" system and how it's used to encourage participation (or "more hoops" as he puts it) from other authors. He notes that this situation mostly relates to those new to the tool and community and suggests that it just doesn't work (and really is unnecessary). He ends the post with a call to "end the madness" and move to a standardized role that would allow developers to publish without pushing people away and making them feel unwelcome.

SitePoint PHP Blog:
CRUD (Create Read Update Delete) in a Laravel App
May 25, 2015 @ 09:49:11

The SitePoint PHP blog continues their series around the creation of a basic CRUD (create, read, update and delete) application with PHP. In this second part of the series they build on the simple application in the first part and enhance it with the remainder of the CRUD handling.

In the previous part, we've bootstrapped our Laravel CRUD application by creating the database, some controllers, basic routes and simple views. In this part, we'll wrap things up and implement proper CRUD.

He jumps right in and creates the controller action and view to take in new "Task" information. This includes the installation of the Illuminate HTML package and setup of the needed provider and facades. He shows how to create the Task model and hook the results of the request into it and make the new record. This includes some basic "required" validation too. He then shows how to read and display the list of current tasks as well as setting up the edit and delete actions for each task.

NetTuts.com:
E-mail List Alternatives With PHP Using Mailgun's List API
May 25, 2015 @ 08:12:15

In a new tutorial posted to the NetTuts.com site they show you an alternative method for sending emails from your PHP application: using the Mailgun API. This API provides an interface into the Mailgun service, specifically made for sending emails without the hassles of hosting your own email server.

Over the past couple years I've run into various frustrations with both open source email list applications and paid cloud-based providers. In this tutorial, I'll guide you through my adoption of Mailgun.com, an economical solution I've been using successfully now for two years. [...] Mailgun is a cloud-based SaaS email cannon, like SendGrid. It's actually free for up to 10,000 emails per month. Mailgun is incredibly powerful and offers a well-documented API in a variety of popular languages. It provides for both send and receive capabilities, the latter of which can be quite difficult to develop from scratch. While Mailgun doesn't provide templates for rich HTML newsletters, it provides a platform upon which you can build anything.

He shows you how to use the service using a simple "ListApp" application (found on GitHub here) that provides some of the most common email list management functionality. He shows you how to set up a free Mailgun account and where to find their PHP SDK for the PHP integration. He then gets into the code examples, showing how to connect to the API via the SDK and doing tasks such as:

  • Creating and update a mailing list
  • Importing members to a list
  • Showing a list of current list subscribers
  • Send a new message
  • Synchronizing lists and members

He ends the post with a quick section about extending the ListApp application (or the PHP SDK) with a suggestion to add better error reporting or a queue system to manage the remote API requests more efficiently.

Nate Krantz:
How I'm Writing Unit / Functional Tests
May 22, 2015 @ 10:50:42

In a recent post Nate Krantz has shared some of his own methods around writing functional and unit tests.

So...testing. That thing that everyone says is so important but you don't really learn about it in school. I've had some trials and tribulations with testing so I'm going to just dump out some thoughts here.

He starts with a bit of background on his own experiences in development and how he finally decided that testing would "solve everything". He started with unit tests (for a CodeIgniter application) and how he got them up and running. He talks about issues he found around dependencies (and static methods) and how he made use of mocks to reduce some of the issues with dynamic loading, at least how CodeIgniter does it. Unfortunately, this didn't work out as planned so he fell back to a test database and create more effective and simpler functional tests. Code examples are sprinkled through out the post to show how he was trying to solve the problem at different points in the process.
