VirtPHP

The evolution of PHP from a mere server-side scripting language to a full-fledged general-purpose programming language hasn't gone unnoticed in the recent years. To top that, the innovative versions of PHP that are being launched into the web market on a regular basis have added fuel to the ever-rising popularity of the web development software. If you're a PHP developer, you might have come across a situation where you need to switch from one PHP version to another. Well, just like Ruby and Python, now even PHP has effective tools for dealing with the concept of switching between multiple versions of PHP. Today, through this blog, I'll be highlighting the features of two such awesome PHP tools that have helped in managing and installing multiple PHP versions conveniently. These tools are: PHPBrew and VirtPHP. So, let's take a closer look at the features of these amazing PHP tools.

Firstly, let's get to know PHPbrew better

Released in the year 2012, PHPbrew is a fabulous PHP tool that allows PHP developers across all skill-levels to build and install multiple PHP versions by placing the same into a folder that's located within your home directory.
