Symfony2 components overview Process
by Chris Cornutt April 18, 2014 @ 12:41:41

The ServerGrove blog has posted their latest Symfony2 component spotlight, this time focusing on the Process component.

The Symfony2 Process component, allows us to execute commands in sub-processes. [...] The Process component provides an object-oriented abstraction on top of proc_* functions to execute independent processes from PHP.

As with the other posts in the series, they walk you through the installations via Composer and some examples of its use. The post also shows the use of exit codes, working with long running processes and how to execute PHP code in the command. They also briefly look "under the hood" at how the component does what it does (on top of the proc_* functions).

Interview Tom Oram and Rob Allen
by Chris Cornutt April 18, 2014 @ 11:33:39

Continuing on in the "Can Great Apps Be Written in PHP?" series on the SitePoint PHP blog, Matthew Setter talks with Tom Oram and Rob Allen of Nineteen Feet about some of their experience with the language and some of the technology they've used (and recommend).

In our second interview, we talk to Tom Oram, who works for a small development firm in Wales and Rob Allen, from Nineteen Feet. These two developers have a solid wealth of PHP experience and knowledge and have helped me refine my ideas and approaches on many occasions.

The questions include:

  • What lead you to PHP?
  • What have been the highlights or redeeming features?
  • Do you see yourself moving to another language in the future?
  • How have you implemented deployment?
  • What testing tips can you share?

Check out the full post for Tom and Rob's answers.

Jacques Woodcock - The PHP Community Is Much More Than PHP Codes or Frameworks
by Chris Cornutt April 18, 2014 @ 10:14:49

In the latest in their series of PHP community interviews, the 7PHP.com talks with Jacques Woodcock one of the leaders in the Nashville PHP community and of the Nashville PHP User Group (see his previous interview for more on that). In this interview they focus on some quotes from Jacques posted on the SouthernAlpha startup Twitter account about giving back to the community.

The 'level of wisdom' in them was too strong to be left there, I had to bring it out and I'm thankful to Jacques 'TheKit' Guy for sharing with me (and hence you) his precious experience he gained down the years and elaborating more on those quotes.

They go through each of the quotes and let Jacques expand on them a bit - why he got started with the community, some ways that people can get involved in their local group and remembering that a community is made up of more than just single actors.

Edd Mann:
Tuples in PHP
by Chris Cornutt April 18, 2014 @ 09:48:38

Edd Mann has a new post today sharing some of his exploration into implementing tuples in PHP. A tuple is a common data structure in other languages consisting of an immutable, ordered list of items.

Since exploring languages such as Scala and Python which provide the tuple data-structure, I have been keen to experiment with how to clearly map it into a PHP solution. Tuples are simply a finite, ordered sequence of elements - usually with good language support to both pack (construction) and unpack (deconstruction) of the values. I have found that many use-cases of the common place array structure in PHP could be better suited to n-tuple's. [...] I discussed briefly that what makes tuples so powerful in the highlighted languages is their good support for handling their contents, for example unpacking a user tuple into separate id and name variables. PHP supports this form of unpacking in regard to arrays using the 'list' function, which I frequently use to return multiple values from a function/method invocation.

He shares the code for his basic implementation, extended from the SplFixedArray, and shows an example of it in use. He also includes samples showing how to make typed tuples via a "type" method call.

SitePoint PHP Blog:
Getting Started with PHP Underscore
by Chris Cornutt April 17, 2014 @ 13:50:28

The SitePoint PHP blog has a new article posted showing you how to get started with Underscore, a PHP library ported over from Javascript's popular Underscore.js library with many of the same methods intact.

If you've ever used the Backbone framework for JavaScript, you'll already be familiar with Underscore. Indeed, it's become incredibly useful for JavaScript developers in general. But did you know that it's been ported to PHP? [...] Underscore describes itself as a "utility belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects. It's the tie to go along with jQuery's tux, and Backbone.js's suspenders."

He starts by showing you how to get it installed and some of the basic syntax of the methods it defines (basically replace the period with the double-colon) for both the procedural and OOP handling. He shows examples of a few of the more handy methods it provides including:

  • Each
  • Pluck
  • Minimum and Maximum
  • Filter and Reject
  • sortBy
  • groupBy

...and many more. There's also a bit of talk about templating and extending the library via "mixins".

Routing Overview & Basics in Symfony 2
by Chris Cornutt April 17, 2014 @ 12:10:12

If you're relatively new to using the Symfony2 framework, you might be wondering about some of the things happening during requests to your application. One of these things is the routing and handling of each request. In this new post from NetTuts.com they introduce you to the foundations of Symfony2 routing in a screencast.

In the last video, I said we'd take a look at controllers next, but I actually feel it may be easier to learn the framework in a slightly different order. Instead, we're going to learn about the basics of Symfony 2 routing, to give our applications clean and pretty URLs and make it easy to manage our applications URLs and links. We're not going to get too detailed, as Symfony's routing can do quite a bit, but we'll at least cover what we need to know by keeping it straight and to the point.

The screencast is a bit less than 10 minutes long and provides an overview of the routing, how it interacts with bundles and controllers. There's also a bit about using annotations to help define routing information directly in the controller.

Edd Mann:
Storing PHP Sessions/File Caches in Memory using TMPFS
by Chris Cornutt April 17, 2014 @ 11:19:59

Edd Mann (of the Three Devs & A Maybe podcast) has shared a method of session storage he worked up to help increase performance in his application. He shows how to store sessions in memory with the help of TMPFS.

Yesterday I was looking through some application logs and noticed a significant bottleneck with I/O reads in the implemented file cache. [...] This was when I found 'tmpfs', saving me from all sorts of issues relating to adding yet another application to the production stack. 'tmpfs' appears as a mounted partition on your system, however, under the hood it allocates and uses a section of physical memory (non-persistent through reboots). [...] his results in the desired speed boosts, without tampering with the application logic itself. Even better, if the mount is unsuccessful for some reason, it will safety fall-back to using the persistent hard-disk solution.

Since PHP sessions make it easy to change the "save_path" location for the data in an ini value, setup is easy. He includes the needed configuration change and the commands you'll need to mount the tmpfs partition on your local file system.

Sameer Borate:
PHP applications on Google App Engine
by Chris Cornutt April 17, 2014 @ 10:40:02

Sameer Borate has posted a guide to his site today showing you how to get started with PHP applications on the Google App Engine now that it natively supports it (well, mostly).

A couple of years back if you needed to run PHP on Google App Engine you were required to use a open source tool like Quercus, a 100% Java implementation of PHP, to run your PHP applications on the App Engine. However, as you would have guessed, it was not easy to work as with using a native PHP implementation. Now that App Engine natively supports PHP and MySQL, you can easily write PHP applications.

He walks you through the setup and configuration of the App Engine SDK to interact with the service and shows how to create a simple "Hello World" PHP application and deploy it. He talks some about the overall advantages of using the Google App Engine for your application including the scalability it offers and the secured infrastructure it runs on. He finishes the post looking at the different options for data storage and how sessions should be handled (hint: memcache).
