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

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.
