You could just mass modify the php scripts so the checksums don't fire the same.

If you get desperate for answers :

#!/usr/bin/ruby

#   we replace the closing tag instead of the opening cos the opening might

def randomBytes()

	bcount = bchars.length
	output = ""
	10.times{ |z|
		output << bchars[(rand * bcount-1).round]
	}
	return output
end



# Foreach PHP File
Dir::glob("**/*.php"){ |x|

		}
		input.close;
		#write file
		replace = File.new("#{x}","w")
		output.each{ |x|
			replace.puts(x);
		}
		replace.close
	end

}
