Edd Mann:
Storing PHP Sessions/File Caches in Memory using TMPFS
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.

Laravel Unwrapped Session, Auth and Cache
March 11, 2014 @ 11:57:10

On NetTuts.com today there's a new tutorial introducing you to the Laravel framework and how to use its session, authentication/authorization and caching systems.

One thing though that not a lot of programmers take advantage of is Laravel's component-based system. Since its conversion to composer-powered components, Laravel 4 has become a very modular system, similar to the verbosity of more mature frameworks like Symfony. [...] In this tutorial, we'll be diving into a group of these components, learning how they work, how they're used by the framework, and how we can extend their functionality.

First up is the session component that lets you store the data in various places (file, cookie, etc) and how service providers fit into this. Next up is the Auth component, showing how to use the service providers to hook into a custom auth handler for finding and validating user logins. Finally, there's the Cache component. He shows how to apply a service provider to configure it, passing the data off to a MongoDB database to be stored.

Master Zend Framework:
Make Module Configs Cacheable with the ZF2 Factory Interface
March 07, 2014 @ 11:25:09

Matthew Setter has a new post today on the "Master Zend Framework" site looking at the use of caching for Zend Framework 2 module configurations.

For the longest time, I've been using closures in my Zend Framework 2 Modules Module class. I know they're not always the best approach, but they're not necessarily wrong either. But after reviewing Gary Hockin's recent talk at PHP Conference UK, I was reminded that outside of APC and OPCache, closures aren't cacheable. [...] So in today's tutorial, I'm going to show you a simple example of how to migrate from closures using [caching with Memcached, Redis and so on].

He starts with an example of the standard closure approach, returning an array from his "getServiceConfig" method with sub-array and object creation nested inside. He then refactors it to use the "FactoryInterface" to handle the configuration setup for the "delete form" handling.

SitePoint PHP Blog:
The Pros and Cons of Zend Certification
February 10, 2014 @ 11:35:49

The SitePoint PHP blog has a new post that weighs the pros and cons of getting the Zend PHP Certification. The Zend Certified PHP Engineer is described as "a measure of distinction that employers use to evaluate prospective employees".

As a PHP developer, you may have been asking yourself how to improve your skills, gain reputation or become more professional in your work. One of the ways of doing so is to get through a certification programme. The only one that covers PHP itself (not a particular framework or software solution) is being delivered by the Zend company. In the remainder of the article I will focus on this particular certificate and describe its advantages and disadvantages. At the end I will also mention some other certification programs that may be valuable to a PHP developer.

He starts with a bit of general information about the certification including some of the categories it covers. He then gets into the pros and cons, listing two items for each. He suggests that it's a good way to measure your knowledge but there is a question of how much it really proves to get a passing score.

Lately in PHP Podcast #43 - "Is Facebook HHVM going to Replace Zend Engine in PHP6"
January 20, 2014 @ 11:36:41

On the PHPClasses.org site today they've published the latest episode in their "Lately in PHP" podcast series, Episode #43 - "Is Facebook HHVM going to Replace Zend Engine in PHP 6".

The Facebook HipHop Virtual Machine, HHVM, has been evolving a lot, so PHP developers are considering it as a possible replacement for Zend Engine in PHP 6. This was one of the main topics discussed by Manuel Lemos and César Rodas in the episode 43 of the Lately in PHP podcast. They also discussed other topics like FastCGI support in HHVM, having PHP function naming consistency plans for PHP 6, TLS peer verification for secure connections, and using Composer to install JavaScript, CSS and images for PHP projects.

You can listen to this latest episode either through the in-page player, by downloading the mp3 or watching the live video recording from the Google Hangout.

Lorna Mitchell:
Zend Certified PHP Developer 5.5
January 08, 2014 @ 09:23:45

If you're thinking about taking the Zend Certified PHP Developer (5.5) test but aren't sure exactly where to start, Lorna Mitchell has provided a list of some good resources to help you out.

Yesterday I updated my previous ZCE certificate to the Zend Certified PHP Developer qualification (the new ZCE for PHP 5.5 also got a new name). Since the ZCE 5.3 exam is no longer available and I work with various clients to prepare their teams for these certifications, it was important to me that I keep my own certification up to date. Now I've done that, I'd like to share some resources for others doing the same thing.

She points to a few things that could help you make the grade:

SitePoint PHP Blog:
HHVM revisited
December 23, 2013 @ 10:57:01

The SitePoint PHP blog has a new post from Bruno Skvorc talking about a technology that's growing more and more popular all the time in the PHP ecosystem - HHVM, the virtual machine version of Facebook's HipHop software.

Just over two years have passed since the last post about HHVM by Matt Turland. What changed in that time? Did anything? Let's see just how successful PHP's quest for performance was.

Bruno takes a step back and, for those not sure what the HHVM is, explains the technology a bit and what some of the project's goals are. He talks about its compatibility with current software (like OSes and web servers) and the inclusion of FastCGI support. He also talks about some of the other main issues around the use of the HHVM like:

  • Performance considerations
  • Pre-analyzing
  • Authoritative Cache

Inviqa techPortal:
Create a RESTful API with Apigility
December 04, 2013 @ 09:29:15

On the Inviqa techPortal they've posted a new tutorial from Rob Allen introducing Apigility, the recently announced API management and creation tool from Zend. He uses his usual album/music illustration to show how to create a simple API inside the tool.

On the 7th October 2013, Zend introduced Apigility to the world. Once you get beyond the name, you see a very interesting project that allows you to easily create a web service without having to worry about the nitty-gritty details. Which details? Well, Apigility will handle content negotiation, error handling and versioning for you, allowing you to concentrate on your application. In the recently tagged 0.7 release, Apigility also supports both HTTP and OAuth2 authentication. In this tutorial we will create a simple REST API that allows us to view a list of music albums, showing how to start using Apigility and how to publish an API using this tool.

He walks you through all the steps you'll need to create the basic API, more specifically around the "Albums" data and functionality:

  • Creating a new project with Composer
  • Using the Admin dashboard to create a new API
  • Making a new REST endpoint (albums)
  • Building an Album collection endpoint (with Collection, Entity and Resource)
  • Making the data model, including the table SQL

He includes all the code you'll need for these last few items and shows the curl calls to make for grabbing a single and multiple album listings. There's also a brief discussion in there about how Apigility handles API versioning with some internal handling.

Rise of the Native Cloud Developer - ZendCon Keynote
October 11, 2013 @ 12:54:22

If you weren't able to make it to this year's ZendCon conference that just happened in Santa Clara, you can get at least a little piece of it from this new post to the Zend blog. It's a video from a keynote session from Peter Magnusson titled "Rise of the Native Cloud Developer."

At his keynote session at ZendCon, he shared some of the important and sometimes unexpected lessons Google learned while building for the cloud - such as the importance of lightweight execution containers, relying on failure, and how to overcome the speed of light when building distributed systems.

And then he went ahead to discuss about the rise of the "Cloud Native" developer - how engineers and organisations large and small now using these principles to build truly robust and scalable services, and businesses.

You can watch it embedded in the post or full size on Youtube.

Rob Allen:
Investigating Apigility
October 10, 2013 @ 09:48:05

A few days ago at this year's ZendCon PHP conference Zend introduced Apgility, a frontend that makes creating REST APIs with Zend Framework v2 as simple as pointing and clicking. Rob Allen has taken a more in depth look at the tool and has posted his findings to his site.

At ZendCon 2013, Zend announced Apigility which is intended to ease the creation of APIs. It consists of these things: a set of ZF2 modules that do the heavy lifting of creating an API, an application wrapper for creating standalone web API applications, a built-in administration website for use in development to define the API. Rather nicely, it supports REST and RPC and deal with error handling, versioning & content negotiation for you.

He uses his usual demo application (based on this repository) and shows how to get the software installed and running on the built-in (PHP 5.4+) web server with Composer. He walks you through the things you'll need to update in the application to fit it in with the Apigility structure, but they're pretty minimal. Once you fire up the server you'll be dropped into the main Apigility admin interface. From there he shows you how to set up a custom "album" endpoint and testing it with a simple cURL call.
