The SitePoint PHP blog has a new post today with what it calls the eight must- have PHP QA tools to ensure the overall quality of your codebase. These tools cover everything from unit testing out to ensuring code standards are met.

The [QA Tools] site is a simple list of interesting tools that can help you properly test your application, while also analyzing it and producing interesting data for you to look at. This post will be little more than a re-iteration of some of those tools with added information, use cases and advice about them – however, we’re open to expanding this list with other QA tools you throw our way that get plenty of votes in the comments below or seem interesting and/or useful enough.

Their list of eight covers a wide range of QA needs:

• PHPUnit
• Behat
• vfsStream
• PHPLOC
• PHP Mess Detector
• PHP CodeSniffer
• Dead Code Detector
• Copy Paste Detector

For each there's a brief description and some of the commands you'll need to get it installed. Configuring them for your environment is a bit out of the scope of the article, though, so you'll have to pick that up on your own.
