PHP Quality Assurance Tools

[NeilSaunders]

Hi,

I've been developing a PHP site in my spare time, and am trying wherever I can to adhere to best practices, including design principles and coding standards.

At University I completed a group project in java whereby we used an open source tool (Checkstyle) as part of our quality assurance initiative. The idea was you could write a configuration file that defined your codnig standard (Bracket policy - Every method must be commented with @param and @return tags, lines no longer than 80 characters, variable naming conventions, etc), and it would wander an entire package tree and produce an HTML report. It was very, very cool.

What I want to know is are there any similar tools for PHP? I've found this, which looks very promising, but it appears to be a very new project with some as yet unresolved issues. Does anybody know of any more mature tools that exist for PHP?

TIA,

Neil.
