More Useful Jenkins Plugins for PHP Projects

I had 4 builds, before css and js “joint”. Now I have 5, the other stuff is listed fine, just no css… and since it mentions “csslint: No Report” I assume Jenkins recognizes the installation, or am I wrong?
Also - could you elaborate a bit on the “src//*.php" path? taking it “seriously” leads to … well … actually no php files. Does "” dig down the whole folder hierarchy?
