Having picked up both knackered PHP and C projects, PHP is usually worse as the barrier for entry is much lower meaning that the code barely works in most cases. Plus it's usually plugged into turds like WordPress.
Currently dealing with helping someone upgrade a wordpress+buddypress nightmare. Yuck.
C stuff is easier to refactor as well as you have a strict compiler and valgrind on your side.
thats bad and i have always avoided using limited systems like CMSes or Blogs to use as a basis for big systems because of it. But you are right, alot of the PHP community is based around Wordpress, Typo3, phpbb etc but i have been using PHP for 10+ years and apart from installing Wordpress for blogging i have never used that stuff ;)
