I'm not seeing this as an improvement. I'm familiar with PHP coding, and over the past few years the community has come up with a set of standards in the form of the PSR documents (http://www.php-fig.org/psr/). This site doesn't many any allowance for pre-existing standards.
It seems that the idea behind this site is "let's make some software to enable the crowd-sourcing of the standardization process". That may be a good idea, but (1) I'm not sure that this is needed, and (2) I'm not sure who the target audience is.
