If you need a little help to start using Vagrant there are three services that might be useful:
- [Rove][rove]: service that allows you to pregenerate typical Vagrant builds, PHP among the options. The
provisioning is made with Chef.
- [Puphpet][puphpet]: simple GUI to set up virtual machines for PHP development. **Heavily focused in PHP**. Besides
local VMs, can be used to deploy to cloud services as well. The provisioning is made with Puppet.
- [Protobox][protobox]: is a layer on top of vagrant and a web GUI to setup virtual machines for web development. A single YAML document controls everything that is installed on the virtual machine.

Recursion, a feature that allows a function to call itself, is supported by the language, but most of the PHP code focus
is on iteration.
Anonymous functions (with support for closures) have been present since PHP 5.3 (2009).
PHP 5.4 added the ability to bind closures to an object's scope and also improved support for callables such that they
PHP 5.4 added the ability to bind closures to an object's scope and also improved support for callables such that they
can be used interchangeably with anonymous functions in almost all cases.
The most common usage of higher-order functions is when implementing a strategy pattern. The built-in `array_filter`
