Protect your PHP code with SourceGuardian
It's the best day of the week again ;)

A packed edition this week, including the latest podcast from the recently established Elephant In The Room team. Listen to their "deep exploration of Value Objects".

We have the new book from Cal Evans, out last week and titled Signalling PHP: Catching Signals in PHP CLI Scripts. Why not use the most popular language on the web to create tools on the server?

With the announcement of the PHP UK Conference in London next February, it's time to get yourself those Early Bird tickets for two days of amazing talks, great socials and the most up to date information and training on PHP.

Have a great weekend PHP people.



A Peek At Aura v2 -- Aura.Web
Paul Jones writes - In the lessons learned post a few weeks ago, I wrote about how Aura was born of the idea that we could extract independent decoupled packages from Solar and how, in doing so, we discovered that some of those extracted packages themselves could be further split into independent pieces. The last example of this was how we extracted Aura.Dispatcher from three separate packages. Today, I’m going to talk about how the Aura.Web v2 package has been slimmed down as a result of Aura.Dispatcher being created. (Incidentally, Aura.Web v2 is also PHP 5.3 compatible!)

Is Ghost Really a WordPress Killer?
When you think about blogging platforms, WordPress is generally the obvious and popular choice. What started out as a clean framework for publishing to the web has now grown into a full­y fledged CMS aimed at tackling entire websites. What about those people looking for a simple and effective way to write to the web without the overhead of a feature rich CMS? Enter Ghost, a barely one month old blogging platform hoping to meet those less complicated needs.

The Difference Between Class and Type
Whenever you instantiate an object in PHP, you automatically create an object with an implicit type. In fact, you can “type hint” on just about any object in PHP, whether it’s a concrete object, an interface or an abstract class. Yet in object oriented development, there is in fact a distinct difference between an object’s class and type. Brandon Savage explains.

Tutorials and Talks

Clustered File Systems and PHP
In part one, Introduction to Clustering in PHP, we explored the concepts of load balancing, PHP sessions and how to set up a rudimentary PHP cluster that allows for redundancy as well as load balancing. The final configuration was one load balancer exposing an NFS share for all of the client PHP servers to use for session storage. While effective, this still gives us a single point of failure (the load balancer). More load balancers can be added, but this sits us squarely back on our original problem: All of the sessions are on the first load balancer, not the second.

How to Use the Twilio API To Send an SMS Message
Businesses are taking advantage of the ubiquity of mobile devices and SMS. This tutorial describes how to send an SMS message to a phone with PHP. We will be using the Twilio API, which provides numerous communications services. For example, with Twilio you can make and receive phone calls through the browser, mobile or desktop, send and receive SMS and MMS messages, or handle short codes.

Nginx Reverse Proxy with PHP-FPM and MySQL
Simple tutorial on how to configure two nginx servers using reverse proxy with php-fpm and mysql support and running them behind iptables firewall with other nginx security features. In this tutorial will use two separate servers “Dedi” (dedicated server) which will act as our private back-end server and “VPS” (virtual private server) which will act as our public front-end server. The purpose of this is to use small VPS that are seen to the public, yet use power of the dedicated server which is hidden.

Parsing CSV Files in PHP: Checking The File Type
Tom McFarlin writes - When it comes to parsing CSV files, the way you go about doing it is relatively the same (hence the need for the standard format, right?): 1.Read the file; 2.Break each line into an entry into a collection; 3.Iterate through the collection; 4.Create an object or element with attributes based on the data in the current given line. Sure, this is a high-level view of how it’s done and your specific implementation may have finer nuances, but – as I mentioned – I think its safe to say that the way we go about parsing a file is the same regardless of what we do with the data once we start reading it.

Social Network Style Posting with PHP, MongoDB and jQuery - Part 1
Post mechanisms similar to Facebook are nowadays very common within any application. The concept of Post-Like-Comment is familiar to everyone who ever used a social network. In this article, we will learn how to create a similar working model wherein the user will be able to post his status, like posts and comment on them. What’s more interesting is that after learning things from this article, going forward you will be able to implement a lot of other features on your own.

How to Run A Web Server from A PHP Application
Normally we deploy our PHP applications in a webserver (such as apache, nginx, …). Gonzalo Ayuso used to have one apache webserver on his personal computer to play with his applications, but from time to now he prefers to use PHP’s built-in webserver for experiments. It’s really simple.

Yii Routing, Active Record and Caching
Almost all modern web apps have 3 major concerns: Retrieving data from a database easily and effectively, caching the web content and URL rewriting to create user friendly URLs. Yii, like any other good framework, offers simple and easy solutions to all of the above. In his previous article Sandeep Panda covered the basics of building a simple CRUD app with Yii. In this tutorial he looks at how Yii greatly simplifies the development of database driven websites with its Active Record support. Additonally, Yii lets you further improve your websites by implementing user friendly URLs and powerful caching techniques.

PHP Performance Crash Course, Part 2: The Deep Dive
Dustin Whittle wrote Part 1 on this series back in May, when he covered some basic tips for optimising performance in PHP applications. In this post he dives a bit deeper into the principles and practical tips in scaling PHP.

Beyond Object Oriented Programming
In his previous post, Beyond Inheritance, Anthony Ferrara talked about looking past "types" and reasoning about objects differently. His conclusion was that inheritance wasn't necessary for OOP and often results in more problems than it solves. In this follow up he looks beyond that and explores more of what will come from treating objects as containers of behaviour. Let's look at what this means for various kinds of classes.

Money Pattern: The Right Way to Represent Value-Unit Pairs
The Money Pattern, defined by Martin Fowler and published in Patterns of Enterprise Application Architecture, is a great way to represent value-unit pairs. It is called Money Pattern because it emerged in a financial context and we will illustrate its use mainly in this context using PHP.

Create Your Own Picture Processor in PHP
Using just a web server and the PHP scripting language, it’s easy to build a simple image editor with many of the features of top photo editing packages.

An enumeration implementation for PHP. In terms of software development, an enumeration (or "enumerated type") is essentially a fixed set of values. These values are called "members" or "elements". An enumeration is used in circumstances where it is desirable to allow an argument to be only one of a particular set of values and where anything else is considered invalid.
