Laravel is a PHP framework developed with developer productivity in mind. Written and maintained by Taylor Otwell, the framework is very opinionated and strives to save developer time by favoring convention over configuration. The framework also aims to evolve with the web and has already incorporated several new features and ideas in the web development world—such as job queues, API authentication out of the box, real-time communication, and much more.
In this article, we’ll explore the ways you can build—and test—a robust API using Laravel. We’ll be using Laravel 5.4, and all of the code is available for reference on GitHub.Continue reading →
Understanding the Input/Output (I/O) model of your application can mean the difference between an application that deals with the load it is subjected to, and one that crumples in the face of real-world uses cases. Perhaps while your application is small and does not serve high loads, it may matter far less. But as your application’s traffic load increases, working with the wrong I/O model can get you into a world of hurt.Continue reading →

If you haven’t been working with PHP lately, you might wonder what happened to PHP 6. Why the skip from PHP 5 to PHP 7? Well, long story short, PHP 6 was a failure. To avoid confusion, the new version was renamed PHP 7.
PHP 7 introduces a number of new features, while at the same time dropping depreciated SAPIs and extensions. As a result, it tends to outperform PHP 5.x by a wide margin. Some compatibility issues could pose a problem, but most developers have nothing to worry about.
In this post, Toptal Freelance Software Engineer Vilson Duka explains what makes PHP 7 different, and why it’s time to make the switch.Continue reading →
Developers sometimes run into tasks that require access to email mailboxes. In most cases, this is done using the Internet Message Access Protocol, or IMAP. As a PHP developer, I first turned to PHP’s built in IMAP library, but this library is buggy and impossible to debug or modify. So today we will create a working IMAP email client from the ground up using PHP. We will also see how to use Gmail’s special commands.Continue reading →

If it ain’t broke, don’t fix it.
It’s a well known phrase, but as we know, most of the human technological progress was made by people who decided to fix what isn’t broken. Especially in the software industry one could argue that most of what we do is fixing what isn’t broken.
Fixing functionality, improving the UI, improving speed and memory efficiency, adding features: these are all activities for which it is easy to see if they are worth doing, and then we argue for or against spending our time on them. However, there is an activity, which for the most part falls into a gray area: refactoring, and especially large scale refactoring.Continue reading →

I live in Córdoba, Argentina, approximately 130 kilometers (~80 miles) away from the lake where I kitesurf. Thats roughly a two-hour drive, which I can deal with. But I cant deal with the fact that weather forecasts are inaccurate. And where I live, good wind conditions last just a couple of hours. The last thing you want to do is clear up your Monday schedule to go kitesurfing and find yourself cursing the gods on a windless lake after two hours of driving.
I needed to know the wind conditions of my favorite kitesurfing spot—in real time. So I decided to build my own weather station.Continue reading →
Everyone has their own set of tools. As a PHP developer, one of my favorites is a Rapid Application Development framework called “Nooku”. In the words of the development group: “Nooku is more of a web development toolkit than a framework”
In case you are not familiar with it, have a look. It’s an open source project that makes heavy use of industry accepted design patterns to produce highly componentized applications that are easily extensible and reusable (initially created by one of the lead Joomla developers). Out of the box, Nooku gives you a great deal to help get projects off the ground faster. A small, but strong sample:Continue reading →
