The PHP syntax chacker has been modified so that it can run several variants of PHP either on the same server or distributed over several servers to make it easier to check different versions of PHP.
The directories icon and styles need only be isntalled on a single server.
Copies of the directory v4 can be installed on the same server or different servers in order to syntax check different versions of PHP.
In v4 only the file config0.php needs to be updated with server specific paths etc. However, you are likely to want to customise the skins as well (syntax-check.php, html/syntax-bad.php and html/syntax-ok.php).
Feel free to hack, edit, mashup and improve, but please include a link back to meandeviation.com as the source.
