## Building and Deploying your Application {#build_title}
If you find yourself doing manual database schema changes or running your tests manually before updating your files (manually), think twice! With every additional manual task needed to deploy a new version of your app, the chances for potentially fatal mistakes increase. Whether you're dealing with a simple update, a comprehensive build process or even a continuous integration strategy, build tools are your friend.

### Control your deployment with Phing
### Phing - Deployment with XML and PHP
With [Phing](http://www.phing.info/) you can control your packaging, deployment or testing process from within a simple XML build file. Phing provides a rich set of tasks usually needed to install or update a web app and can be extended with additional custom tasks (written in PHP).

with additional custom tasks, written in PHP.

### Capistrano - The powerful Ruby alternative
[Capistrano](https://github.com/capistrano/capistrano/wiki) is a system for *intermediate-to-advanced programmers* to execute commands in a structured, repeatable way on one or more remote machines.
It is pre-configured for deploying Ruby on Rails applications, however people are **successfully deploying PHP systems** with it. Successful use of Capistrano depends on a working knowledge of Ruby and Rake.
Dave Gardner's blog post [PHP Deployment with Capistrano](http://www.davegardner.me.uk/blog/2012/02/13/php-deployment-with-capistrano/) is a good starting point for PHP developers interested in Capistrano.
###Chef - Ruby based system integration framework
[Chef](http://www.opscode.com/chef/) is more than a deployment framework, it is a very powerful Ruby based system integration framework that doesn't just deploy your app but can build your whole server environment or virtual boxes.
Chef resources for PHP developers:
* [Three part blog series about deploying a LAMP application with Chef, Vagrant, and EC2](http://www.jasongrimes.org/2012/06/managing-lamp-environments-with-chef-vagrant-and-ec2-1-of-3/)
* [Chef Cookbook which installs and configures PHP 5.3 and the PEAR package management system](https://github.com/opscode-cookbooks/php)
### Continuous Integration
> Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily — leading to multiple integrations per day. Many teams find that this approach leads to significantly reduced integration problems and allows a team to develop cohesive software more rapidly.

There are different ways to implement continuous integration for PHP. Recently [Travis CI](https://travis-ci.org/) has become by far the easiest way to do CI. Travis CI is a hosted continuous integration service for the open source community. It is integrated with GitHub and offers first class support for many languages including PHP.
