virtPHP is a project I kicked off with Jacques Woodcock and Jordan Kasper at Hack Nashville in May 2013. It is a tool for creating and managing multiple isolated PHP environments on a single machine. It’s like Python’s virtualenv, but for PHP.
virtPHP creates isolated environments so that you may run any number of PHP development projects, all using different versions of PEAR packages and different PECL extensions. You may even specify a different version of PHP, if your system has various installations of PHP.
The project is still in the alpha stages, and we welcome contributions. If you’re looking for an open source project to get involved in, this is it!
