Drupal actually rarely requires any PHP coding. There 
					are modules for everything you could need. Customizing a 
					Drupal site often involves more CSS, web design, and 
					back end administration than writing code. However, it 
					is sometimes necessary to add a little PHP code to get 
					the right file path for images in a tricky web design or 
					page layout. On rare occasions you may also need to 
					change something manually in the database to fix a 
					problem.
